3.6 Connecting Process Control Relays
Instructions for setting up this module are in Section 2.1.3 on page 2-4.
The process control connector is embossed with letters identifying each pin. Table 3-2 shows the
letters designating the 3 pins assigned to each of the 6 channels.
1. Using Figure 3-7 and circuit schematics you have prepared, make up a cable to connect the
various system components which are to be controlled. Unambiguous labeling of each lead
will help prevent costly mistakes.
2. Ensure that the Process Control channel override switches are all set to OFF.
3. Connect the component end of the cable to the system component to be controlled.
4. Plug the connector into the back of the Control Unit.
5. Refer to Section 4.11 on page 4-31 for instructions for setting setpoints.

It is the installer's responsibility to ensure that the automatic signals
provided by the product are always used in a safe manner. Carefully check
the system programming before switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation,
always provide for fail-safe operation. As an example, in an automatic
backfill operation where a malfunction might cause high internal pressures,
provide an appropriate pressure relief device.
