GENERAL DESCRIPTION
The Sensidyne Model 9000 Two Channel Digital Controller is designed to display, and
control alarm event switching for two sensor points. Sensor signals may be input as 420mA from transmitters. The Model 9000 is equipped with three alarms per channel
with features such as ON / OFF delays, latching relays and Acknowledge. A dedicated
horn driver circuit for a local audible annunciator is also standard. Two standard 5-amp
alarm relays are configurable via the “alarm voting” menu to make relays trip based upon
various alarm combinations. Real-Time Clock and Calendar are also standard. Options,
such as 4-20mA outputs, discrete relays for each alarm are easily added.
A 128 x 64 pixel graphic LCD readout displays monitored data as bar graphs and
engineering units. System configuration is via user friendly menus and all configuration
data is retained in non-volatile memory during power interruptions. The Model 9000
front panel is shown below in Figure 1.0 displaying the bar graph data screen. The five
button symbols below the display are magnetically activated using the supplied magnetic
wand without opening the enclosure. Opening the enclosure door provides access to the
“touch” keypad as shown in Figure 1.1.

DATA DISPLAY SCREENS
The Model 9000 Controller offers two modes for displaying monitored data. Each are
shown below in Figure 1.2.
Figure 1.2
1.1.1 MAIN DATA SCREEN
The Model 9000 Main Data screen shown at left in Figure 1.2 allows each channel to be
viewed simultaneously. Engineering unit values and bar graph values are both displayed
in real time. Arrows below the bars indicate alarm trip point values, making it easy to
identify channels at or near alarm. The direction the horizontal 45 degree arrow side
points indicates either a HIGH or LOW trip as illustrated in Figure 1.1 where Ch 1 points
right indicating high level trips and Ch 2 points left indicating low level trips. Left and
Right hand arrows located at the ends of each bar graph point towards Channel Alarm
LED’s on the front panel associated with this reading. The 10-digit ASCII fields for
identifying engineering units and Channel ID for each channel are also shown on the
Main Data screen.
1.1.2 BLIND MODE SCREEN
The Model 9000 Blind Mode screen shown at right in Figure 1.2 does not allow viewing
of channel engineering unit values. It only indicates the system’s alarm status and time /
date. Some applications require only alarm status be displayed and prefer monitored
values not be shown. A SECURITY menu (see section 2.40) allows locking the system
so only the Blind Mode screen is available.
1.2
SPECIFICATIONS:
1.2.1 POWER SUPPLY REQUIREMENTS
The Model 9000 is equipped with an integral 15 watt universal AC input / 24 VDC
output switching power supply. Standard Model 9000 AC power requirements are 100240 VAC 50/60 Hz @ .45 amp max (including inrush) and 20 watts steady state, applied
to TB5 on the motherboard. If AC power is not available, the Model 9000 may also be
powered with 10-30 VDC @ 3 watts max applied to TB1 on the motherboard. A back-up
DC power source may also be connected to TB1 for automatic switchover if the AC
power source fails. See Figures 3.0 & 3.1 for wiring information.
4
Model 9000 Two Channel Digital Controller Users Manual
Revision B
The basic Model 9000 consumes only 1.5 watts of 10-30 VDC from the integral power
supply. Optional features, and external devices such as remote transmitters, increase
power consumption as described below:
•
•
•
Discrete Relay PCB option; add 1.5 watt.
4-20mA Output PCB option; add .5 watt.
TB3 terminals 1 & 2 on the motherboard provide a maximum of 350mA output
power for powering of auxiliary external devices such as relays, lamps or transmitters
(see Figure 3.0). Power consumed from these terminals must be included when
calculating system power consumption.
1.2.2 RELAYS
Two mechanical (dry contact) Common Form C relays are standard and may be mapped
to various alarm events as described in section 2.3.1
A six mechanical (dry contact) Discrete Relay option board (see section 3.1.6) provides
dedicated Form C relays for ALARM 1, ALARM 2 and FAULT for both channels.
!
All mechanical (dry contact) relays are rated at 5 Amp for 28 VDC and 250 ~VAC
RESISTIVE loads. IMPORTANT: Appropriate diode (DC loads) or MOV (AC
loads) snubber devices must be installed with inductive loads to prevent RFI noise
spikes.
Solid state relays are rated at 2 Amp 12-280 ~VAC (600Vpk).
Relay wiring should be kept separate from low level signal wiring.

BASIC OPERATION
The Model 9000’s graphic LCD displays monitored data and with the 5-button keypad
also serves as the system’s operator interface. All Model 9000 configuration variables
are entered with this operator interface using SETUP menus accessed by pressing EDIT
from either data screen. This Setup mode may be exited manually by pressing NEXT, or
automatically when no keys are pressed for 5 minutes. Alarm relays and front panel
alarm LED indicators remain active during the Setup mode. Alarm LED’s flash until
Acknowledged by an ALARM RESET when they are turned on. A SECURITY menu
offers a password feature to prevent tampering with Model 9000 parameters.
2.1
SETUP MENU CONFIGURATION
Variables inside the CHANNEL (see section 2.2) and SYSTEM (see section 2.3) menu
trees allow Model 9000 configuration for a wide range of monitoring applications. Select
the desired menu by scrolling with UP/DOWN and then EDIT to enter each menu.
Figure 2.0 illustrates the menus tree for configuring Channel variables on its right side
and System specific variables on the left side. Channel variables affect only the specific
channel selected while System variables are related to features not specific to either
channel.

CHANGING MENU VARIABLES USING THE KEYPAD
Upon entering a menu, a pointer controlled by the UP/DOWN keys indicates the selected
variable. Some are simple YES/NO or ON/OFF entries toggled by pressing the EDIT
key. Others, such as Channel ID and Eunits fields may have many ASCII character
possibilities. Allowed ASCII characters are as follows:
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz blank
space !”#$%&`()*+,-./0123456789:;<=>[email protected] Notice the often used blank character is
located after lower case z and before the exclamation point !. EDIT places a cursor
under the item and UP/DOWN scrolls through each allowed entry. The NEXT key
moves the cursor to the next position within a field. When the field is complete, EDIT
clears the cursor and loads the field into non-volatile memory where it is retained
indefinitely. Without a cursor present, the NEXT key closes open menus in reverse order
and returns the LCD to the data display.
2.2.1 Model 9000 SETUP CONFIGURATION MENUS
The SETUP menu shown in the middle of Figure 2.0 and in Figure 2.1 below is reached
by pressing EDIT with either data display present. This is the entry-level screen to ALL
Channel, System and Security menus. Use the Up/Down keys to move the pointer to the
desired menu and press the Edit key.
Figure 2.1
2.2.2 CHANNEL SETUP ENTRY MENU
The CHANNEL menu shown below in Figure 2.2 allows configuration of all variables
for the selected channel. These are Alarm 1, Alarm 2, Alarm 3, Configure and
Calibrate.

2.2.3 ALARM 1 / ALARM 2 / ALARM 3 SET-UP MENUs
Alarms 1, 2 and 3 have identical menus. The only difference between each is A1 front
panel LED indicators are yellow while A2’s and A3’s are red. Typical applications often
have A1 set at a WARN level, A2 at a HIGH level and A3 at a negative FAULT level.
However, it is important to understand there is no functional difference between A1, A2
and A3. Since their configuration menus are identical, only one is shown in Figure 2.3.
Figure 2.3
•
•
Set Point is entered in engineering units and determines the value where the alarm
trips. For example, if a channel monitors 0-50 ppmH2S and the desired alarm level is
10 ppm, the correct entry is 10.00. A one percent dead band prevents alarm chatter.
This means after tripping an alarm the input must move at least 1% of full scale back
through the setpoint for the alarm to auto reset.
The ON Delay / OFF Delay entries allow ON and OFF time delays affecting how
long the trip-point must be surpassed before an alarm event transition occurs. ON
delays are limited to 10 seconds while OFF delays may be as long as 120 minutes.
Delays are useful in many applications to prevent nuisance alarms and unwanted
cycling into and out of alarm conditions.
9
Model 9000 Two Channel Digital Controller Users Manual

•
Low Trip is set to NO for increasing alarms or YES for decreasing alarms to
determine if the alarm activates upon exceeding or falling below the set-point.
Latching determines either manual or automatic alarm reset operation. YES
requires a manual Alarm Reset to unlatch the alarm even though an alarm condition
no longer exists. YES also causes this alarm’s common relay, front panel LED, and
optional discrete relay to latch. NO allows all outputs for this alarm to automatically
reset as soon as the alarm condition clears.
Discrete LED indicators on the front panel indicate the status of each alarm. Any new
alarm event causes the associated LED to flash until an Alarm Reset occurs causing an
acknowledged steady on condition. Operators should recognize new alarms by a flashing
LED. Alarm Reset also acknowledges, or deactivates, audible devices driven by the
AUDIBLE ALARM option connector J2 (see Figure 3.1)
2.2.4 CONFIGURE MENU TO DEFINE CHANNEL
The next channel setup menu after the alarm menus is CONFIGURE. It allows setting
Name and EUNIT ASCII fields, defining the measurement range, and how many decimal
points of resolution the reading will have.
Figure 2.4
2.2.4a NAME / EUNITS ASCII DATA FIELDS
The first two items in this menu are for entering the 10 character channel Name and
engineering unit ASCII fields. Name should describe the channel’s data in user
terminology such as a tag # or other description. Eunits should define the units of
measure for what this channel is to display. Several standard Eunits fields are available
by pressing EDIT but if these are inappropriate, a CUSTOM field allows editing of each
character. Section 2.2 describes how to modify these fields using the keypad.
2.2.4b INPUT MEASUREMENT RANGE
The ZERO / SPAN menu entries allow configuration of the measurement range
displayed by this channel. Measurement Range defines the range of the input signal’s
engineering units. For example, if a channel’s input is 4-20mA from a transmitter
monitoring 0 to 10ppm chlorine, then the Zero value should equal 0.000 and the Span
10
Model 9000 Two Channel Digital Controller Users Manual
Revision B
value equal 10.00. Four digits must entered so trailing 0’s may appear here that are not
displayed on other data screens.
2.2.4c DECIMAL POINT RESOLUTION
Resolution of the displayed channel value is configured in this menu by setting the
number digits trailing the decimal point. Displayed readings are limited to a maximum of
four digits with a polarity sign. Auto-ranging displays the highest resolution allowed by
this menu’s decimal point entry. For example, a range of 0 to 100ppm and two decimal
points reads 0.00 at 0ppm and 100.0 at 100ppm. This may be undesirable due to the high
resolution at zero unless the sensor’s output is extremely stable. If decimal points are
limited to one, the 0ppm reading becomes 0.0 and the 100ppm reading remains 100.0.
Resolution may be limited further by setting decimal points to 0 where in the above
example, 0ppm reads 0 and 100ppm reads 100.
2.2.4d TURNING OFF UNUSED CHANNELS
The Channel Active? menu entry asks if this channel is to be utilized. OFF causes the
controller to never process inputs applied to this channel and no alarms are tripped or
data displayed. Inactive channels have a line drawn through them on the Setup screen to
indicate it is turned off.
2.2.5 CAL SETUP MENU
The Model 9000 CAL MODE features supports pushbutton calibration of zero and span
values. This feature should be utilized only when there are no other zero/span controls
within the monitoring system since it is inappropriate to calibrate a signal at more than
one point. Therefore, if calibration will be performed at another transmitter or
monitoring device, the Model 9000 CAL MODE feature should not be used.
The CAL SETUP menu allows entering the correct Zero Gas & Span Gas set-point
values needed to calibrate the sensor. These are entered in the same engineering units as
input range.
Figure 2.5
11
Model 9000 Two Channel Digital Controller Users Manual
Revision B
2.2.6 CALIBRATE INPUT MENU
Pressing EDIT with the arrow pointing at the CALIBRATE INPUT item in Figure 2.5
displays the Ch CALIBRATE menu shown in Figure 2.6. To prevent false alarms,
relays are inhibited in the Ch CALIBRATE menu and 4-20mA outputs (if equipped) are
held at 1.5mA. These conditions remain until the Ch CALIBRATE menu is exited AND
the Cal Delay period described in section 2.4 is complete. Cal OFFSET & Cal GAIN
controls in this menu allow pushbutton calibration by moving the pointer to each and
pressing the EDIT key. The bottom menu item is a live reading of the channel’s Output
value made available for calibration checks to see if an adjustment is needed.
Unintentional calibrations may be reset by the Set UNITY menu item. Set UNITY
resets Cal OFFSET to 0 & Cal GAIN to 1 which is useful for returning the calibration
to a known starting place. Sensor aging may be monitored by recording zero and span
readings at Unity Gain when the sensor is new, and again later when degradation may
have occurred. The A/D Counts value indicates the raw output of the 10-bit analog to
digital converter. In Unity Gain, 200 A/D Counts = 0% of the input range and 1000
A/D Counts = 100%.
To check zero calibration, apply the Zero Gas calibration value to the sensor and
observe the live reading. If the zero reading differs from the zero setpoint, a calibration is
needed. To calibrate zero, move the pointer to Cal OFFSET and press EDIT. A
warning message explains that pressing EDIT again will change the zero calibration and
NEXT will exit. The procedure for span calibration is identical. For example, if a 0-100
ppm H2S sensor is to be spanned with 50 ppm H2S span gas, the Span Gas set-point
must be 50. If 45 ppm is to be used later, the Span Gas set-point must be changed to 45
to match the span calibration gas. If the live reading is only 40 ppm with the 50 ppm gas
applied a span calibration is needed. Move the pointer to the Cal GAIN entry and press
EDIT twice. Unity Gain may be used at anytime to cancel incorrect calibrations and
start again.

SYSTEM CONFIGURATION MENUS
Some items needing configuration are not specific to a channel but affect the entire
Model 9000 system. These are located in the system entry menu shown on the left side of
12
Model 9000 Two Channel Digital Controller Users Manual
Revision B
Figure 2.0. System menus are accessed by pointing to the desired item and pressing
EDIT.
Figure 2.7
2.3.1 RELAY 1 / RELAY 2 MENUS
The Relay 1 & Relay 2 menus are identical except Relay 2 has an acknowledge
feature. All other Relay 1 & Relay 2 features are identical and therefore are discussed
only once.
Figure 2.8
•
The Set Relay Logic menu shown below in Figure 2.9 offers additional “voting”
flexibility by controlling the channel alarm combinations that will trip this common
alarm relay. “OVR” on the menu’s right side stands for override and means ANY of
the selected alarms will activate the relay. The “OR” / “AND” columns work
together based upon the following logic equation:
[AND column selections] ANDED WITH [OR column selections] = relay
activation.
For example, if Ch1A1 & Ch2A1 are selected in the AND column and Ch1A2 &
Ch2A2 are selected in the OR column, the logic equation is [Ch1A1 AND Ch2A1]
13
Model 9000 Two Channel Digital Controller Users Manual
Revision B
ANDED WITH [Ch1A2 OR Ch2A2]. This requires both A1’s along with either A2
to activate the relay.
Figure 2.9
•
•
•
Failsafe controls relay activation for the common relays. Failsafe ON causes these
relays to de-energize during alarm conditions and energize when there is no alarm.
With Failsafe active, a power failure forces the relay contact to the alarm position.
Horn controls how activating this relay will affect the horn driver circuit connected
to J2 on the motherboard. Choices are NO, STEADY or PULSE. Warning level
alarms might be set to pulse the horn with high alarms set for steady. Personnel then
know which alarm level is present by hearing the pulsing or steady horn.
Turning Acknowledge ON (not available on Relay 1) allows Relay 2 to be
deactivated during alarm conditions by an Alarm Reset. This is useful if another
audible device is being driven by the relay. The acknowledge feature is not available
for Relay 1 since it is often used for driving a warning light and Relay 2 for driving a
horn. It could be dangerous if an operator acknowledged the horn AND the light
since no indication of the high alarm condition remains.
2.3.2 HORN / PIEZO MENU
• The Model 9000 display PCB is equipped with a small audible piezo that chirps when
keys are pressed providing an audible feedback to the operator. It also may be set to
audibly indicate alarm conditions by entering YES into the Piezo On menu item in
Figure 2.10. This piezo will then mimic the Horn settings menus described in
section 2.3.1.
•
The Horn ACK menu item determines if the Horn Driver output may be
acknowledged by an Alarm Reset. YES causes an Alarm Reset to silence the horn
even though an alarm condition remains active.

2.3.3 COMM PORT MENU
The system Comm Port menu allows setting baud rate and RTU address for the slave
Modbus serial port. This slave port may be used to transfer Model 9000 data to a host
device such as a PC, PLC, DCS or even another R. C. Systems Controllers. The slave
port is addressable, allowing many Model 9000 controllers to be connected to a single
RS-485 cable.
2.3.4 CLOCK / DELAYS MENU
• The Model 9000 monitors signals from sensors that may require varying times to
stabilize after power is applied. The Warm Up Delay menu item allows setting how
long alarm relays remain disabled after power is applied.
•
Cal Delay determines how long alarm relays are inhibited after completing a
calibration.
•
The Model 9000 is equipped with a 24-hour clock and calendar. Time and Date
menu items are for setting the correct time and date. Time of day must be entered in
24 hour mode so for example 6:00:00 PM = 18:00:00.

SYSTEM SECURITY MENU
A 4-digit Pass Code entered and confirmed in this menu item locks all menus. Viewing
menus is not denied but attempts to edit variables flashes the Locked message on the
LCD.
Authorized individuals locking the system should first enter a name, phone #, or other
contact information into the 12 character field on the top line of the Security screen. To
lock or unlock the system the correct 4 digit authorization number must be entered into
the Pass Code field. It is very important to remember the 4 digit code since the factory
must be consulted if it is lost.

INPUT / OUTPUT OPTIONAL PCB’s
P1, P2 and P3 connectors on the motherboard offer unique positions for I/O options
described in this section. A screen appears briefly after power up indicating what options
types are connected.
3.1.1 ANALOG INPUT PCBP/N 299-0002-01 (10-0221)
Transmitter input PCB option, shown in Figure 3.2, is available for interfacing the Model
9000 to field transmitters with 4-20mA or voltage outputs (0-2 VDC max). TB1 provides
Channel 1 & Channel 2 + / - terminals for receiving analog inputs. R1 / R2 are 100 ohm
precision socketed termination resistors between each channel’s signal + and - 4-20mA
input terminals. These may be removed if voltage inputs are to be applied. TB2 provides
2-terminals connected to the Model 9000 internal 24 VDC power supply for powering
external transmitters. Figure 3.3 shows correct wiring for both 2-wire and 3-wire
transmitters.

3.1.2 OPTIONAL DISCRETE RELAY PCB’s P/N 299-0003-01
The optional Discrete Relay PCB (10-0222), shown in Figure 3.4, adds six 5 amp form C
relays. Each relay is associated to one of A1, A2 or A3 for channel 1 or 2. Many Model
9000 applications utilize the standard equipped Relay 1 / Relay 2 (see section 2.3.1) and
do not require optional discrete relays for each of the 6 alarms events (2 A1’s, 2 A2’s & 2
A3’s).
!
All mechanical (dry contact) relays are rated at 5 Amp for 28 VDC and 250 ~VAC
RESISTIVE loads. IMPORTANT: Appropriate diode (DC loads) or MOV (AC
loads) snubber devices must be installed with inductive loads to prevent RFI noise
spikes.
AC or DC power supplies to relays on the Discrete Relay PCB option must be the same
for each relay. Example: 24VDC should not be the power switched by one relay and
115VAC by others.

OPTIONAL 4-20mA ANALOG OUTPUT BOARD P/N 299-0004-01)
An optional 4-20mA analog output board (10-0223), shown in Figure 3.5, may be added.
Each channel’s output will transmit 4mA for 0% readings and 20mA for 100% readings.
If the Model 9000 primary power is 100 – 240 VAC, 4-20mA outputs are capable of
driving 20mA through a 750 ohm load. Outputs are self powered and DC power should
not be provided by the receiving device.

Model 9000 NEMA 4X WALL MOUNT ENCLOSURE
The Model 9000 wall mount NEMA 4X enclosure is shown in Figure 4.0. Non-metallic
enclosures are not grounded by metal conduit. For internal ground points to be grounded
to earth, the TB5 – GND terminal must have a proper earth ground connection (see
Figure 3.1).
!
CAUTION: NONMETALLIC ENCLOSURE DOES NOT PROVIDE
GROUNDING BETWEEN CONDUIT CONNECTIONS. USE GROUNDING
TYPE BUSHINGS AND JUMPER WIRES. ALL FIELD WIRING MUST HAVE
INSULATION SUITABLE FOR AT LEAST 250V.
