Entek 6622LS/6622HS/6622NB Protection Monitor
Terms and Conditions
ENTEK IRD INTERNATIONAL CORPORATION
GENERAL TERMS AND CONDITIONS
1.
CONTRACT. When Customer accepts a Quotation from Entek IRD International Corporation or an
affiliate (the entity issuing the quotation being “Entek IRD”) by issuance of a purchase order or otherwise
and Entek IRD accepts the order, Customer is deemed to have agreed to all the Terms and Conditions
contained herein. Unless otherwise approved in writing, the acceptance of Entek IRD is expressly
conditioned upon Customer accepting these Terms and Conditions, and any different or additional terms
and conditions contained in Customer's order or related documents are expressly objected to by Entek IRD
and not binding upon it. Entek IRD reserves the right to accept or reject all orders received by it and all
orders may only be accepted at the contracting office of Entek IRD located in Ohio. Entek IRD may accept
in writing, by commencement of performance or otherwise.
2.
QUOTATIONS. All quotations expire automatically thirty days from date of quotation or earlier by
notice from Entek IRD. Unless otherwise noted in writing by Entek IRD, all prices are F.O.B. the place of
origin for domestic shipments and Ex Works (as defined in INCOTERMS 1990) for international
shipments; and risk of loss in transit is on Customer. Prices do not include any applicable taxes, however
designated, levied or based upon the goods or services being quoted. Customer agrees to pay all such taxes
or provide acceptable evidence of exemption therefrom.
3.
TIMING. All delivery/shipping and service dates stated by Entek IRD are approximate dates only and
estimated in good faith to the best of Entek IRD's ability and are dependent upon Entek IRD's prompt
receipt of all necessary information from Customer. Time shall not be deemed to be of the essence in
Entek IRD’s performance of this agreement, and no penalty clause of any description in any specification
or order will be effective unless specifically approved in writing by an authorized officer of Entek IRD. In
any event delivery/shipping and service dates are always quoted subject to unavoidable delays due to
causes beyond Entek IRD’s control including but not limited to strikes, casualty, war, acts of God, or
government action.
4.
TERMS. Payment terms for domestic orders are net 10 days from date of invoice, unless otherwise
provided in the quotation. For international orders, Entek IRD reserves the right to specify prepayment,
letter of credit, or payment net 10 days from the date of invoice. Each shipment shall be considered a
separate and independent transaction and payment must be made accordingly. If the financial condition or
credit of Customer at any time in the judgment of Entek IRD, does not warrant shipment of goods ordered,
Entek IRD may at its option require full payment prior to shipment or refuse to ship and terminate any
order outstanding without liability to Entek IRD. Should Customer become delinquent in the payment of
any sum due, Entek IRD shall not be obligated to continue performance. If any amount is not paid when
due, to the extent permitted by law a late fee of 1% per month (or any part thereof) shall be charged on past
due amounts until paid.
5.
CANCELLATION. Once accepted by Entek IRD, an order is not subject to cancellation in whole or in
part by Customer without Entek IRD's prior written consent. Any such cancellation shall be subject to a
cancellation charge as determined by Entek IRD to cover any loss that may be incurred by Entek IRD as a
result of such cancellation, including without limitation a 25% restocking charge for standard products.
6.
CUSTOMER RESPONSIBILITIES. Customer shall be solely responsible for the accuracy and
adequacy of the information provided to Entek IRD, and Entek IRD shall not be liable for any damages
resulting from the loss, disclosure or inaccuracy of such information. Customer shall, for those contracts
which include on site installation, have the installation site prepared at its expense prior to the scheduled
installation date to enable Entek IRD to promptly deliver and commence installation. The equipment is not
for use in or with any nuclear facility, unless the Quotation expressly permits such use; and Customer shall
indemnify and hold Entek IRD harmless from all liability (including such liability resulting from Entek
IRD’s negligence) arising out of such improper use. Customer shall not send or use the products outside
the United States except in compliance with all applicable law, including U.S. export regulations and
restrictions.

SOFTWARE AND SERVICES DOCUMENTS. If any computer software, whether incorporated into a
piece of equipment ("firmware"),or provided separately, and related user documentation in any medium
(together referred to as "Software") are included in the contract, the terms of the Entek IRD Standard
Software License Agreement shall govern the contract with respect to Software. If any services are
included in the contract, the Entek IRD Standard Field Engineering Services Terms and Conditions shall
govern such services. Those documents are available to Customer upon request, and Customer is
responsible to obtain and read the Standard Software License Agreement and the Standard Field
Engineering Services Terms and Conditions.

LIMITED WARRANTIES AND REMEDIES.
A. Entek IRD warrants to Customer (and not anyone else) that all equipment manufactured by Entek IRD
shall be free of defects in materials and workmanship under normal conditions for a period of one (1) year
from the date of shipment (except that items with limited life such as batteries and lamps are warranted for
90 days from date of shipment).
B. With respect to any Entek equipment which fails to satisfy the limited warranty provisions in this
Section, as Customer's exclusive remedy, and at Entek IRD's option, Entek IRD will repair or replace the
product or refund its purchase price, provided that any defect in the product is brought to the attention of
Entek IRD within the warranty period. To qualify for this warranty Customer must return the defective
product to Entek IRD’s designated facility freight prepaid, and after repair or replacement Entek IRD will
return the product freight prepaid; or, if in Entek IRD’s opinion the product is impractical to ship,
Customer shall be charged for labor, transportation and subsistence expenses for the service
representative(s) providing the warranty work at Customer’s site. Entek IRD alone will be authorized to
furnish or arrange for repairs or replacements.
C. The above limited warranties do not apply, and no warranty, either express or implied, shall be
applicable, (a) to damage resulting from accident, alteration, misuse or abuse, harmful conditions or Act of
God; (b) if the product is not installed, operated and maintained according to procedures recommended by
Entek IRD; or (c) if the Entek IRD serial number is obliterated. In no case shall the limited warranty
extend to defects in materials, components, or services furnished by third parties or to the repair or
installation of the product performed by third parties. The above warranties do not extend to any
equipment sold "as-is" or "as-inspected;” no warranties, either express or implied, are made with respect to
such products.
D. Entek IRD makes no representations or warranties to Customer, or anyone else, with respect to
equipment manufactured by a third party. Any warranties of the third party manufacturers shall run
directly to Customer to the extent permitted by law and Entek IRD shall have no liability therefor.
E. The limited warranties in this Section constitute Entek IRD's entire warranty as to the products provided
hereunder. ENTEK IRD HEREBY DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING CONFORMITY TO ANY REPRESENTATION OR DESCRIPTION AND
INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY
PARTICULAR PURPOSES WHATSOEVER.

THAT NO OTHER REMEDY (INCLUDING, BUT NOT LIMITED TO, INCIDENTAL OR
CONSEQUENTIAL DAMAGES, LOST PROFITS, LOST SALES, LOST PRODUCTION,
OVERHEAD, LABOR, INJURY TO PERSON OR PROPERTY, OR ANY OTHER INCIDENTAL
LOSS) SHALL BE AVAILABLE TO CUSTOMER. THIS ALLOCATION OF RISK IS REFLECTED IN
THE PRICES OF THE PRODUCTS. ENTEK IRD'S MAXIMUM LIABILITY HEREUNDER ARISING
FROM ANY CAUSE WHATSOEVER SHALL BE LIMITED TO THE PURCHASE PRICE OF THE
PRODUCTS IN QUESTION. Any suit related to this Agreement, on any legal theory, must be
commenced within one year after the cause of action accrues.

10. TITLE AND LIEN RIGHTS. The equipment shall remain personal property regardless of how it is
affixed to Customer's real property and Entek IRD reserves a purchase money security interest in the
equipment until the purchase price has been fully paid. Customer agrees to execute, and hereby appoints
Entek IRD as its attorney-in-fact to execute on Customer's behalf, any documents requested by Entek IRD
which are necessary for attachment and perfection of its security interest. If Customer defaults, Entek IRD
shall have all the rights of a secured creditor under the Uniform Commercial Code as enacted in Ohio.
11. OTHER TERMS. These terms and conditions and any issue, claim or dispute arising hereunder shall be
interpreted under and governed in all respects by the internal laws of the State of Ohio, and not by the
1980 U.N. Convention on the International Sale of Goods. These terms and conditions and the written
quotation to which they relate constitute the entire contract between the parties, and supersede all other
oral or written statements of any kind whatsoever made by the parties or their representatives. Waiver by
Entek IRD of strict compliance with any one or more of these Terms and Conditions is not to be
considered a continuing waiver or a waiver of any other term or condition. No statement purporting to
modify any of these terms or conditions shall be binding unless expressly agreed to in writing signed by an
officer of Entek IRD and by Customer.

1.
LICENSE: This License Agreement ("Agreement") sets forth the terms and conditions on which software
owned by or licensed to Entek IRD International Corporation ("Entek IRD"), whether incorporated into a
piece of equipment (i.e. "firmware") or provided separately, together with related user documentation in
any medium (together referred to as "Software"), are licensed to a customer ("Customer"). Upon
Customer's use of or payment for the Software, Customer is deemed to have agreed to all the terms and
conditions contained in this Agreement. Any different or additional terms and conditions contained in

A. Entek IRD grants Customer a non-exclusive and non-transferable license to use each Software program
furnished hereunder solely for Customer's internal use and subject to the following limitations: If the
Software provided is for a single-user system as identified in the quotation, Customer may use the
Software only on a single computer. If the Software provided is for a local area network (LAN) multi-user
system as identified in the quotation, Customer may install the Software on a single database server and
may access the Software only from other network clients located at the same site. If the Software provided

access, Customer may use only security keys purchased from Entek IRD.
B. Customer acknowledges that the Software and related documentation including all versions,
corrections, enhancements and improvements thereto, include confidential data and know-how which are
claimed as trade secrets or other proprietary information by Entek IRD and/or its suppliers. Without prior
written consent of Entek IRD, Customer shall not do, or permit or assist others to do any of the following:
(i) allow the Software, related documentation or any portion thereof in any form to be used by any person
or entity other than Customer's employees or agents, and then only to the extent necessary in the scope of
their employment or agency; (ii) copy or otherwise reproduce, disassemble, modify, update, translate,
transform into other form, or enhance the Software; or (iii) disclose or permit access to the Software to any
person or entity, except to the extent necessary to facilitate the permissible use thereof as set forth in (i)

C. Customer shall not assign or otherwise transfer the license to the Software granted herein except to a
successor in interest to the entire business in which the Software is used, and then only if the assignee or
transferee agrees in writing to be bound by the terms hereof. Customer warrants that all persons having
access to the Software will observe and perform the obligations set forth in this document. Customer
understands and agrees that the Software is an unpublished work and agrees that the existence of any
copyright notice shall not be construed as an admission or presumption that publication has occurred.
Customer acknowledges, notwithstanding the license granted herein, that the Software, and all rights
thereto, are and shall continue to be exclusively owned by Entek IRD and/or its suppliers. The Software is
"commercial computer software" for purposes of licenses to any divisions or agencies of the U.S. Federal
Government. Customer shall not send or use the Software outside the United States except in compliance

LIMITED WARRANTIES.
A. Entek IRD warrants to Customer (and not anyone else) that all Entek IRD Software supplied by Entek
IRD shall perform in substantial conformance with the specifications provided by Entek IRD in the
product manual of such Software for a period of one year from the date of shipment. Entek IRD does not
warrant that the operation of the CPU or Software will be uninterrupted or error free. Entek IRD makes no
representation or warranty, either express or implied, with regard to the Software's suitability, capacity, or
performance in relation to Customer's specifications or needs. Entek IRD warrants that the Software does
not contain computer viruses when shipped. It is Customer’s responsibility to preserve the integrity of its
computer systems and to conduct virus checks of all Software before it is installed, and this warranty
concerning computer viruses expires when the Software is installed.
B. With respect to any Entek IRD Software which fails to satisfy the limited warranty provisions in this
Section, as Customer's exclusive remedy, and at Entek IRD's option, Entek IRD agrees to repair or replace
such defective item without charge, or Entek IRD's sales price therefor shall be refunded upon return of the
defective product to Entek IRD, provided that any defect in the Software is brought to the attention of
Entek IRD within the warranty period; Entek IRD alone will be authorized to furnish or arrange for repairs
or replacements, or refund of Entek IRD's sales price within the terms of this limited warranty.
C. The above limited warranties do not apply, and no warranty, either express or implied, shall be
applicable, (a) to damage resulting from accident, alteration, misuse or abuse, harmful conditions or Act of
God; (b) if the product is not installed, operated and maintained according to procedures recommended by
Entek IRD; or (c) if any modifications whatsoever to the Software are made by anyone except Entek IRD.
In no case shall the limited warranty extend to defects in materials, components, or services furnished by
third parties or to the repair or installation of the product performed by third parties.
D. The limited warranties in this Section constitute Entek IRD's entire warranty as to the Software
provided hereunder. ENTEK IRD HEREBY DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING CONFORMITY TO ANY REPRESENTATION OR DESCRIPTION AND
INCULDING IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY
PARTICULAR PURPOSES WHATSOEVER.
3.
PATENT AND COPYRIGHT INDEMNITY. Entek IRD will at its expense, defend Customer against
any claim that any Entek IRD Software furnished under this Agreement infringes a United States patent or
copyright. Entek IRD will pay all costs, damages and attorney's fees that a court finally awards as a result
of such claim. To qualify for such defense and payment, Customer must 1) give Entek IRD prompt written
notice of any such claim, and 2) allow Entek IRD to control, and fully cooperate with Entek IRD in, the
defense and all related settlement negotiations.
Customer agrees that if the operation of the Entek IRD Software becomes, or Entek IRD believes is likely
to become, the subject of such a claim, Customer will permit Entek IRD at its option and expense, either to
secure the right for Customer to continue using the Entek IRD Software or to replace or modify it so that it
becomes non-infringing. However, if neither of the foregoing alternatives is available on terms which are
reasonable in Entek IRD's judgment, Customer will return the Entek IRD Software upon Entek IRD's
written request. Entek IRD will grant Customer a credit for any Entek IRD Software whose total charges
are fully paid, as Customer's sole remedy and Entek IRD shall have no other liabilities therefor.
Entek IRD shall have no obligation with respect to any such claim based upon Customer modification of
any Software or its combination, operation or use with apparatus, data or programs not furnished by Entek
IRD or in other than the specified operating environment. This Section states Entek IRD's entire obligation
to Customer regarding infringement or the like.

6622LS/6622HS/6622NB Monitor
This manual introduces you to the Entek 6622LS, 6622HS,and 6622NB protection monitor.
It is intended for anyone who installs, tests, configures, or uses the 6622LS/6622HS/
6622NB protection monitor. This manual covers the 6622LS/6622HS/6622NB with the
version 5.02 firmware. Unless otherwise noted, this manual uses “6622” to describe all three
monitors.
Introduction
The Entek 6600 Series protection monitors are part of a modular protection system for
critical machinery. Each monitor is a stand-alone unit, using a separate power supply, relays,
and wiring termination unit. The 6600 Series protection monitors meet the intent of, and in
many cases, exceed the API 670 standard for protection monitoring. Each monitor in the
6600 Series fulfills a different role in providing comprehensive machinery protection.
Monitor Description
The 6622 protection monitor provides continuous monitoring of the input signal from
accelerometers, velocity sensors, and non-contact probes. The 6622 independently monitors
the overall value for each input channel. You can define both high pass and low pass filters
to limit the frequency bandwidth of the signal. The 6622 can perform single-integration to
convert acceleration to velocity, or velocity to displacement. In addition, the 6622
continually compares the band-limited overall value to the Alert and Danger alarm
setpoints.
If you connect a tachometer input (1 pulse/rev), the 6622 calculates the magnitude and
phase values for the first three orders. It also calculates an FFT spectrum with a maximum
frequency of 6 times the machine speed (180 to 7500 RPM). For higher speed machines, the
monitor calculates the FFT spectrum with a maximum frequency of 3 times the machine
running speed (maximum machine speed 15000 RPM). If there is no tachometer input
signal and the high pass filter (HP FLT) is set above 5 Hz, the 6622 calculates the FFT
spectrum over a 1 kHz bandwidth, and cannot provide order-based information. If there is
no tachometer input signal and the high pass filter (HP FLT) is set to 5 Hz or less, the
spectrum is limited to a maximum frequency of 200 Hz.
The monitor stores the last 30 minutes of values (1/minute) for each channel, as well as the
last calculated spectrum. In the event of a Danger alarm, or a “first out” danger alarm
message from another monitor, the 6622 stores this data in a separate memory area. A “first
out alarm” is the first alarm in an interconnected series of monitors. This allows later
analysis of the data leading up to the event that caused the Danger alarm. You can retrieve
any of this data from the monitor using the MODBUS protocol through a 4-wire multi-drop
serial interface.
Caution: Do not connect the monitors to the transducers until you are sure of the power
connections. Transducers could be damaged if the transducer supply is not correct.

Monitor Description
Application
The 6622 is appropriate for monitoring vibration on rotating machinery in a wide variety of
configurations. This includes monitoring vibration on casings or bearing pedestals, where
an accelerometer or velocity sensor gives an output signal proportional to the absolute
vibration at the mounting point.
Accelerometers are preferred for this application because of their wider frequency response.
The accelerometer signal is typically integrated to velocity because velocity is less
dependent on frequency. Velocity gives a better approximation of the energy in the vibration
signal.
The 6622LS is used as a vibration monitor for biased pickups with sensitivities down to
10 mV per unit. The 6622HS is also for biased pickups but with higher sensitivities up to
1080 mV per unit.
The 6622NB is used as a velocity meter with inputs from non-biased sensors. The sensor
system typically consists of a seismic velocity pickup mounted on a direct-contacting,
spring-loaded shaft rider. This sensor system provides a direct measure of absolute shaft
motion relative to free space.

Monitor Description
Special Considerations
There are several possible configurations of 6622LS/6622HS/6622NB monitor and 6691
power supply for special applications. For more information on configuration of the power
supply, refer to the manual on 6600 monitor power supplies and backplanes.
6622NB
The 6622NB is designed to detect an open circuit fault to a non-biased transducer. Note that
TX HI must be set at 6.00 volts or less. This is for use in systems where the maximum
measured signal is less than 10 volts peak-peak at the input to the monitor.
6622LS
The 6622LS has increased responsiveness for use with low sensitivity transducers. This is
for use in systems where the maximum measured signal is less than 2 volts peak-peak at the
input to the monitor.
6622HS
The 6622HS is responsive to high sensitivity transducers (1080 mV/unit). This is for use in
systems where the maximum measured signal is less than 40 volts peak-peak at the input to
the monitor.
6691/ICP
This version of the 6691 power supply and backplane is for use with the 6622HS or 6622LS
for ICP accelerometers.
6691/-18
This version of the 6691 power supply and backplane provides a -18 VDC output for use
with sensors requiring a -18 VDC power source.
6691
This version of the 6691 power supply and backplane provides a standard -22 VDC output
for use with sensors requiring negative power.

Basic Operation
Basic Operation
This section describes the day-to-day operations for the 6622 protection monitor. It includes
the steps to use the display backlight, display alternate pages, reset the relays after an alarm
(if the alarm relays are set to latching), and display the firmware version. It also describes
the status messages that may appear on the display.
Display Backlight
The backlight makes it easy to see the 6622 display, even in dim light. When the system is
functioning properly and no signals are in alarm, the backlight is off. However, in case of an
alarm or transducer failure, the 6622 automatically turns on the backlight to alert you.
To turn on the backlight, press and release the LIT button. The backlight remains on for
about 3 minutes, after which it automatically turns off. If you press and hold the LIT button
for 5 seconds, the backlight remains on for 10 minutes.
You can manually turn off the backlight by pressing the LIT button once. Note that if the
backlight is on because of a fault condition, you cannot turn it off until the fault or alarm
condition is corrected. If the alarm relays are set to latching (LATCHED option, page 26),
you must also reset the alarm relays with the RES button before the backlight turns off.
Displaying Alternate Pages
The 6622 has two display pages. The first is the one pictured on page 4, and shows the two
bar graphs. To display the second page, press and release the DIS button.

RPM
The 1x machine speed if a tachometer input signal is present; this field
may not appear or does not update if there is no tachometer signal.
BIAS
The DC bias voltage reading for the two channels; the top value is for
channel 1, the bottom value for channel 2.
To return to the first display page, press and release the DIS button. For information on
changing the monitor’s serial address or the clock settings, see “Configuration” on page 15.
Manually Resetting Relays
You can configure the 6622 so that you must manually reset the alarm and System OK
relays after an alarm. This feature is controlled by the LATCHED option on the RELAYS
submenu (page 26). To reset the alarm relays for a monitor, press and release the RES
button. The monitor displays the “LOCAL RELAY RESET” message, then returns to the
display page after resetting the relays.
Note: This resets the relays only if the input is no longer in alarm or the fault condition is
corrected.

This message appears when the vibration level exceeds the Alert alarm
setpoint. The number indicates the channel that exceeded the Alert alarm
setpoint. The underline indicates that the channel was the “first-out” alarm
for this monitor (or series of monitors if interconnected).
This message appears when the vibration level exceeds the Danger alarm
setpoint. The number indicates the channel that exceeded the Danger alarm
setpoint. The underline indicates that the channel was the “first-out” alarm
for this monitor (or series of monitors if interconnected).
This message appears when the Danger alarm relays are manually
inhibited with the INHIBIT option on the User menu (page 17).
This message appears when the start-up multiplier is active. You set the
multiplier with the MULT option on the RANGE 1 and RANGE 2 menus
(page 23). You turn this feature on with the MULT option on the DELAYS
submenu (page 27). While this message appears, the alarm setpoints and
display range are multiplied by the MULT factor.
This message appears when the Danger alarm relays are inhibited (set with
the STARTUP option on the DELAYS submenu, page 27).
Note: The monitor backlight turns on and remains on while any of these messages appears on the
screen. This helps alert you to an alarm or a problem condition.

Since the velocity sensor does not use current from the 6691 power supply, the polarity
of the supply voltage on terminal 4 does not matter.

Some high-output velocity sensors require a special version of the 6622 monitor. For
example, the Entek 544 requires the 6622NB and the Entek 580 requires the 6622HS.

Configuration
This section describes how you configure the 6622. The 6600 Series protection monitors are
very easy to configure. All the controls to configure a 6600 monitor are on the front panel of
the monitor. There are no jumpers or DIP switches that you must set to configure the
monitor. The 6622 has two levels of configuration:
!
User menu - This menu allows you to set the date and time, set the Alert and Danger
alarm setpoints, and inhibit the Danger alarm relays.
!
Factory menu - This menu allows you to configure all the other parameters, including
MODBUS communications, transducer and tachometer input, display scaling, start-up
multiplier, band pass filters, noise floor, transducer checks, alarm relay operation,
number of channels, and API response time compliance.
General Configuration Instructions
All the configuration menus function in the same way. In short, the steps are:
1.
Press and hold two buttons to display the desired menu.

monitor from responding within the required time, you must set this
option to NO.
EXIT
Exit from the Factory menu, save all changes, and return to the display

Note: If you configure the 6622 to use only one channel (CHANS = 1), make the following
adjustments to avoid alarm or transducer failure messages on channel 2:
!
Set the Alert and Danger alarms for channel 2 to their maximum value. See “User menu
options” on page 17.
!
Set the transducer bias values for channel 2 to the largest possible range (-12 V to
+12 V). See “TX OK submenu” on page 25.
CHECK API message
If you see the “CHECK API” message when you try to exit the Factory menu, it means that
you have made a selection that prevents the monitor from complying with a response time
of less than 100 milliseconds. If you want to use a configuration that requires a longer
response time, you must set the API option on the Factory menu to NO.
Often this is the result of setting the HP FILT option on the RANGE 1 or RANGE 2 menu to
a low value (below 10 Hz).

mil rms, mil rpk, mil rpp, µm pp, mm pp, ins pp). Note that the units that
are neither rms nor pk are average values (sum of amplitudes divided by
number of samples).
MX SIG 1
Choose the maximum expected signal input to the monitor
(0.1–99999.9). This is in the transducer engineering units peak-to-peak.
Note that this does not set the full scale for the monitor. See “Setting MX

SCALE 1
Choose the full scale value for the monitor (0.01–9999.99 eu). This also
sets the display full scale and the 20 mA point for the 4–20 mA outputs.
MULT 1
Choose the alarm multiplier (0.1–100.0). When you set MULT in the
DELAYS submenu to YES, the monitor multiplies all the alarm setpoints
and display scale for channel 1 during the start-up period. The start-up
period is defined by the STARTUP option in the DELAYS submenu
(page 27).
A value of 1 does not change the alarm setpoints at all. Values greater
than 1 increase the setpoints so that the machine can pass through critical
speeds without tripping an alarm.

Setting MX SIG
The MX SIG option allows you to use a configuration that would otherwise cause the OUT
OF RANGE message to appear. The monitor assumes a maximum input voltage by
combining the maximum amplitude (SCALE value) at the highest frequency (LP FLT). This
protects you from a configuration that would overload the 6622 and possibly prevent it from
functioning properly.
WARNING: Reducing the MX SIG setting may allow you to clear the OUT OF RANGE message by
entering a configuration that could overload the 6622 and prevent it from functioning
properly.
In some cases, however, the actual maximum voltage might be less than the voltage
calculated by the 6622. In those cases, by reducing MX SIG, you can force the monitor to
accept a configuration where the worst-case maximum input voltage would overload the
monitor. This could, for example, allow you to increase the frequency range by increasing
the LP FLT setting.
This is particularly important for integrated measurements (acceleration to velocity or
velocity to displacement). For non-integrated measurements, setting MX SIG to 7000
should provide sufficient range and resolution. For integrated and low-amplitude
measurements, you can use the following example (modified for your configuration) to find
a value for MX SIG.
Transducer sensitivity: 100 mV/g
Display full scale: 10 mm/s rms
High/low pass filters: 10 Hz and 85 Hz (cycles/second)
acceleration (g pk)
= maximum frequency x velocity (mm/sec rms)
= 85 Hz x 10 mm/sec = 1103 mm/sec2 rms
= 1.5 g pk-pk (convert mm to g, rms to pk-pk)
Then multiply by an additional factor of 5 to get the value for MX SIG:
1.5 g pk-pk x 5 = 7.5 for MX SIG.

OUT OF RANGE message
If you see the “OUT OF RANGE” message when you try to exit the RANGE submenu, it
means that you have chosen a configuration that is outside the dynamic range of the
monitor. You cannot exit the RANGE submenu until you choose a valid configuration.
!
For nonintegrating configurations, this message is often caused by setting the TX SNS,
MX SIG (RANGE 1 or RANGE 2 submenu), and/or SCALE too high (too many volts).
!
For integrating configurations, this condition may also involve the LP FLT option. The
monitor assumes a worst case of the full scale amplitude at the highest frequency of
interest (at the low pass filter). In this case, reducing the LP FLT or the MX SIG setting
may clear the message.
!
The MULT option may also cause this message to appear. The 6622 assumes the worstcase of the full scale amplitude times the MULT setting. Reducing the MULT setting
may clear the message.

Failsafe operation
Failsafe operation means that when in alarm, the relay contacts are in their “normal,” deenergized, or “shelf-state” positions. In other words, normally closed relays are closed in
alarm, and normally open relays are open in alarm. With failsafe operation, a power failure
equals an alarm. The following are true of a relay in failsafe condition:
!
The relay is energized when power is applied to the unit.
!
The relay in a nonalarmed condition has power applied to the coil.
!
In alarmed condition, power is removed from the relay coil, causing the relay to change
state.
For failsafe operation, the following are true:
N/C
!
Under normal (nonalarm with power applied to the unit) conditions, the relay closes the
circuit between the common and the N/O (normally open) terminals.

Testing Calibration and Relays
Testing Calibration and Relays
To test the monitor’s calibration, you connect a known signal to the backplane of the
monitor and read the signal from the display on the front of the monitor. You can test the
relays by changing the input signal to cause a relay to change state.
Signal Inputs for Testing
When testing any of the 6600 protection monitors, you must use the correct input signal. For
example, most 6622 configurations for use with an accelerometer expect a bias voltage. If
the input signal does not include the expected bias voltage, the monitor signals a transducer
fault. Please use the following guidelines when setting the input signal:
Note:
!
Set the input signal to a sine wave with a frequency of 100 Hz. This allows you to use
the transducer sensitivities in the table below.
!
The asterisk (*) indicates integrated units.
!
Note that the sensitivity is given in mVRMS. This is the most common setting for
millivolt readings on a multimeter. Make sure your multimeter is set to read voltage in
mVRMS.
Do not use these values for the TX2 SNS and TX2 SNS settings (“RANGE 1 and
RANGE 2 submenus” on page 23)

When testing configurations for accelerometer input with bias, set the input signal DC
bias to halfway between the TX LO and TX HI settings (“TX OK submenu” on page
25). You can get around the need for a bias voltage by setting TX LO to -5.00 and TX
HI to +5.00. If you do this, make sure you reset the TX LO and TX HI values correctly
before putting the monitor back into service.

1.
Ensure that the oscillator frequency is within the monitor passband.
2.
On a 6622, integrating from acceleration to velocity, or velocity to displacement, both
frequency and amplitude of the applied signal determine the value of the derived
parameter. Always verify with counter or oscilloscope.
3.
Signal generator output impedance may be significant when compared to 6600 input
impedance. Always verify input signal amplitude with high input impedance DVM at
the monitor terminal strip.
4.
Test the 6622NB with the velocity sensor test configuration. Do not couple with a
capacitor or offset the signal path when testing the 6622NB.
5.
Transducers may be simulated directly at the backplane as shown or elsewhere. If this
involves application via barriers, ensure that the barrier rating is not accidentally
exceeded.
6.
Nonpolarized capacitor may be substituted if required.

Calibration and System OK Relay Test
The following steps show you how to test the calibration for channel 1. They also test the
function of the System OK relay. To test the calibration for channel 2, substitute the channel
2 terminals.
1.
Connect a signal generator or other known signal source to the channel 1 input
terminals (1 and 2). Refer to “Signal Inputs for Testing” on page 28 for details.
2.
Connect a multimeter to the channel 1 4–20 mA recorder terminals (5 and 6).
3.
Set the input signal amplitude to 50% of the full scale setting for channel 1 of the
monitor. This is the SCALE 1 option on the RANGE 1 submenu (page 23).
programmed range × 0.5 × transducer sensitivity = input amplitude
4.
Look at the 6622 front panel display, and note the digital value for channel 1.
Remember that the monitor displays the channel 1 value when the indicator (a dash) is
over the channel 1 bar graph. The digital value for channel 1 should be the same as the
input signal ± 2.5% of full scale.
5.
Look at the multimeter attached to the 4–20 mA recorder terminals. The meter should
read 12 mA ± 4.5% of full scale. 12 mA is half the range between 4 and 20.
6.
Increase the input signal to 100% of the full scale setting for channel 1 of the monitor.
7.
Look at the 6622 front panel display, and note the digital value for channel 1. The
digital value for channel 1 should be the same as the input signal ± 2.5% of full scale.
8.
Look at the multimeter attached to the 4–20 mA recorder terminals. The meter should
read 20 mA ± 4.5% of full scale.
9.
Decrease the input signal amplitude to 0 (zero).
10. Look at the 6622 front panel display, and note the digital value for channel 1. The
digital value for channel 1 should be 0 (zero) ± 2.5% of full scale.
11. Look at the multimeter attached to the 4–20 mA recorder terminals. The meter should
read 4 mA ± 4.5% of full scale.
12. Test the state of the System OK relay terminals (25 and 26). The System OK relay is
always in failsafe conditions, so it should be in the energized (open) position.
13. Change the input signal bias voltage so that it goes outside the TX LO or TX HI limits
(“TX OK submenu” on page 25). Check to see that the TX FAIL message appears on
the monitor, and that both the display and the 4–20 mA output go to 0 (zero).
14. Test the state of the System OK relay terminals (25 and 26). The state should change to
closed when you change the input signal, indicating transducer failure. Note that the
System OK relay is not subject to the GLOBAL alarm delay (“DELAYS submenu” on
page 27).
Repeat this process for channel 2.

Alarm Relay Test
The following steps show you how to test the monitor alarm relays. Most of the relays
reflect the alarm state (Alert or Danger) of an input channel. There is also a System OK
relay that responds to either channel 1 or channel 2 transducer fault, monitor system failure,
or loss of power. For the steps to test the System OK relay, see “Calibration and System OK
Relay Test” on page 31.
Note: If the LATCHED option is set to YES, you may have to manually reset the relays by
pressing the RES button on the front panel of the monitor. The LATCHED option is on the
RELAYS submenu (page 26).

Testing Calibration and Relays
1.
Connect a signal generator or other known signal source to the channel 1 input
terminals (1 and 2). Refer to “Signal Inputs for Testing” on page 28 for details. When
testing configurations for accelerometer input with bias, set the input signal DC bias to
halfway between the TX LO and TX HI settings.
2.
Connect a multimeter to the channel 1 Alert relay terminals to test for continuity (28
and 29). You could also connect to the channel 1 relay N/O instead of the N/C terminal
(29 and 30).
3.
Using 100 Hz as the input frequency, set the input signal amplitude so it is less than the
Alert setting for channel 1 of the monitor. This is the ALERT 1 option on the User
menu (page 17). Use the transducer sensitivity from the table on page 28.
Alert alarm setpoint × transducer sensitivity > input signal amplitude
4.
If the LATCHED option is set to YES, you may have to manually reset the relays by
pressing the RES button on the front panel of the monitor.
5.
Test the state of the channel 1 Alert relay terminals (open or closed).
6.
Increase the input signal to exceed the channel 1 Alert setpoint so that
Alert alarm setpoint × transducer sensitivity < input signal amplitude
Again, use the transducer sensitivity from the table on page 28 and an input frequency
of 100 Hz.
7.
Test the state of the channel 1 Alert relay terminals. The state should change when the
input signal exceeds the Alert setpoint. Depending on the GLOBAL option setting in
the DELAYS submenu (page 27), it may take up to 30 seconds before the relay changes
state.
8.
Test the state of the channel 1 Danger relay terminals (open or closed).
9.
Increase the input signal to exceed the channel 1 Danger setpoint so that it is above the
Danger alarm setpoint. This is the DANGER 1 option on the User menu (page 17).
Danger alarm setpoint × transducer sensitivity < input signal amplitude
10. Test the state of the channel 1 Danger relay terminals. The state should change when the
input signal exceeds the Danger setpoint. Depending on the GLOBAL option setting in
the DELAYS submenu (page 27), it may take up to 30 seconds before the relay changes
state.
Note: There are two Danger relays for each channel; remember to test them both.
Repeat this process to test the channel 2 alarm relays.

Example - 544 transducer has a sensitivity of 1080 mV/ins/s
Find ins/s in the first column (twice under TX UNT) and look at the 1000 TX SNS row.
Next find the 6600 display units column to find the uncertainity (mil pp is 0.40 typical).
Calculate percent by comparing the Full Scale to be used with the typical measurement uncertainity.
Note:
6622NB is limited to 10 Vpp max signal
6622 is limited to 40 Vpp
