Operation
B 16 position PCB con-
nector
The 16 position PCB connector can be used to connect
optional electrical devices, such as a programmable logic
controller (PLC). If you select the PLC option, you will be
provided a schematic explaining the available electrical
connections.
C Main power switch and
power cable con-
nection
Connect the Heated Valve Drawer to a grounded AC power
source.
The maximum ratings for the connections to the vacuum
pump and Heated Sample Line are 230 Vac, 50 Hz.
The master power switch turns the entire system on or off.

Setting temperature, pressure, and flow
Use the valves and temperature controllers to monitor and control the temperature, flow, and
pressure of gas as it moves through the gas cell.
Setting the temperature set point and alarms
The temperature of each component is controlled using a separate temperature controller. A high
temperature limit will turn the heater off if the primary controller fails.
OVER TEMPERATURE
The temperature controller features an over temperature alarm that alerts you to potential
overheating and shuts off the heater until you intervene. The over temperature limit is 196 °C (384.8
°F). If the limit is reached, the system will need to be manually reset.
To manually reset the system, turn the system off, allow it to cool to room temperature, and then turn
the system back on.
