Before putting the module into operation, you must perform the following procedures:
1. Install the module in accordance with the instructions on pages 16-22.
2. Develop a logic diagram of the process control function.
3. Use Table 3-4 to record the proposed setpoint in volts, corresponding pressure setting, and
activation direction for each relay.
4. Draw a circuit schematic that specifies exactly how each piece of system hardware will connect
to the module relays.
5. If the module will measure the pressure of a gas other than N
2
or air, you
must
adjust the setpoint
relays for the process gas that will be used. See Section 3.3.1.
For application assistance, contact an MKS application engineer at +1-833-986-1686.
Once the module is operating, you may use the module front panel to perform the tasks listed in
Table 3-5.
