2.2
Mounting
Mount the unit on a bench, table top or shelf in a horizontal position and operate
at least ten inches from any air obstructions to the fan, front panel, rear panel,
bottom and top of the unit, in an ambient environment between the specified
5°C to 38°C (40°F to 100°F).
2.3
Ambient Temperature
The CL900A/CL950A is designed to operate within an ambient temperature
range from 5°C to 38°C (40°F to 100°F). Failure to operate the unit within this
range may damage your unit. If the unit is operated in an ambient temperature
above 38°C (100°F) a thermal cutoff switch will cut off power to the heater. The
process variable (PV) will no longer approach the setpoint variable (SV). The
heaters will cool down and cease to operate. If this should occur you should
send your unit back to OMEGA for service.

Temperature Controller:
The temperature controller provides a separate digital display for setpoint
temperature as well as process temperature. Buttons are provided on the front
panel for configuring the controller. The CL900A/CL950A is shipped preconfigured. The customer should not alter any parameters except for the
displayed engineering units (°F/°C).
P.I.D. Indicator:
When this light is illuminated, the unit is heating up the target plate.
NOTE:
P.I.D. Control:
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm used in
high-end temperature controllers. The controller causes the process to attain the desired
temperature by turning the process on or off. The process may be a heater or refrigerator. As
the process temperature approaches the setpoint temperature the hot or cold process will be
pulsed to reduce the corrective measures and minimize overshooting. The controller provides
a visual representation of the process status through LED indicators. An indicator may be lit
continuously, blink or shut off entirely to indicate that the process is on, being pulsed, or off,
respectively.

3.4
Changing the Controller Parameter Settings
The CL900A/CL950A operates at its optimum performance when left with the
factory parameter settings. The only internal parameter that the operator may
need to change is the engineering units (°F or °C). Below are two diagrams: a)
menu hierarchy with factory default settings b) programming procedure. In the
event that some parameters have accidentally been changed, use the factory
default settings shown below.
NOTE:
Changing any other parameter settings besides the engineering units will decrease the
accuracy of your calibrator.

CAUTION:
• Remove all electrical connections and power before attempting any maintenance.
• Never attempt to remove or insert a probe well insert while the probe well is still hot.
1. Pull the probe well insert release pin from the key ring loop, allowing the well
insert clearance for removal. See Figure 2.
2. Remove the probe well insert using the extraction tool (HP-0037). The tool is
first squeezed, inserted into the aperture of the probe well insert (aligning the
pins of the tool with the holes insert). Then relaxed such that the pins separate,
locking into the holes of the insert on either side of the shaft. Pull the pin out
slowly. See Figure 6.

3.7 Fanning System
The CL900/950 has 2 cooling fans. One is mounted just under the top panel. The
other is mounted just behind the rear panel.
The fans are activated whenever the unit is plugged into a live power outlet.
Regardless of whether the power switch is on, the fan will run for a period of 2
hours or until the power is turned off. The fans will remain on as long as the unit
is turned on. Once the the unit is switched from “ON” mode to “STANDBY”
mode the fans will again run for 2 hours. Never disconnect the power cord
while the unit is still cooling down. A safety hazard may result and the unit
may get damaged.

CAUTION:
Never disconnect the power cord while the fan is still cooling down. A safety hazard
may result and the unit may get damaged.
3.8 Overheat Reset Switch
In the event one or both of the fans fail and the temperature inside the unit raise
to an unacceptable level, a thermal cutoff switch will disconnect the heater
power. The controller will still display the desired setpoint temperature,
however, the process temperature will keep falling or not rise at all. At this point
the unit should be sent back to OMEGA for service.

4.3
Fuse replacement
WARNING:
Disconnect power from source before replacing fuse.
CAUTION:
For continued protection against the risk of fire replace with only the same size, type and
rating fuse indicated here and on the rear panel of your unit.
For model:
CL900A/CL950A use
CL900A-230/CL950A-230 use
Fuse, 1 ea. T12A, 250 VAC~, (Time Delay)
VDE APPROVED (1⁄4” dia. x 1 1⁄4 long).
Fuse, 2 ea. T6.3A, 250 VAC~, (Time Delay)
VDE APPROVED (5mm dia. x 20mm long).
NOTE:
Note that for the CL900A-230/CL950A-230 both fuses need to be checked if there is a
suspicion that a fuse has been blown. One or both fuses may have been damaged.
4-1
RS232 Communication
5
Section 5 - RS232 Communication
This method allows bi-directional data transfer via a three conductor cable
consisting of signal ground, receive input, and transmit output. It is
recommended that less than fifty feet of cable be used between the computer and
this instrument. Note that multiple instruments cannot be tied to the same port
in this configuration. The RS232 port is optically isolated to eliminate ground
loop problems.
Below is a pinout diagram for the serial port of the CL900A/CL950A as well as
the pinout for a 9-pin PC serial port. Use a straight DB9(female) to DB9(male)
connector cable to connect your computer to the CL900A. The cable should be
attached when only when the computer and CL900A are off.
Only parameters in the parameter list should be modified or queried via the
serial port. Other parameters should be viewed or queried from the controller,
directly. It is highly recommended that baud rate for the controller be modified
on the controller, directly. Note that both the CL900A and the computer must be
communicating with the same serial communications parameters to establish a
working communication link.
The serial communications feature can be tested using terminal emulation
package. Note that this controller does not time out waiting for the next
character to be transmitted. Be sure not to use the XON/XOFF or hardware
handshaking. Lastly, it should be noted that following a complete transmission
to the CL900A, a response it sent back. If the message was valid, the changed or
queried parameter is echoed back (following the same format). If the message
was not according to acceptable format or was attempting to force a parameter
out of range, an "ERROR" message is echoed.
Note, only RS232 protocol is supported by the serial port. Voltage levels are not
to exceed ±12VDC. A standard 9-wire cable should be used, with shielding and
DB9 connectors. The CL900A/CL950A connections are female. Most computers
have a 9-pin male connection. Hence, a male-female cable with straight through
connections is appropriate for interfacing.

[controller id] – Up to 2 numeric characters, ’00 to ‘99’ (factory default=’01’)
[command] – 1 character, upper case or lower case
‘R’ – To read a parameter from the controller
‘M’ – To temporarily modify a controller parameter (lost upon shutdown)
‘E’ – To modify a controller param. in non-volatile mem. (saved even after
shutdown)
[parameter #] – Up to 2 numeric characters, ‘00’ to ‘99’
<new value> - This control word is used only when entering or modifying a
parameter.
Up to 6 characters may be entered. The first character can be a space, a ‘+’, or a ’‘. The next 4 characters are for entering the new value parameter value. Be sure
to use the exact same field format as is currently being used. (i.e. if the XXX.X
format is used to express temperature, be sure to enter a new value that
conforms to the same format).
<units> - This optional control word is used to specify units, F for °F, C for °C.
[CR/LF] – Every transmission must be terminated with a carriage return [CR]
character.
The line feed [LF] character is optional.
