2 Initial Setup Procedures<br />
2.1.4 Process Control Setup<br />
It is the installer's responsibility to ensure that the automatic signals<br />
provided by the product are always used in a safe manner. Carefully check<br />
the system programming before switching to automatic operation.<br />
Where an equipment malfunction could cause a hazardous situation, always<br />
provide for fail-safe operation. As an example, in an automatic backfill<br />
operation where a malfunction might cause high internal pressures, provide<br />
an appropriate pressure relief device.<br />
1. If you do not have process control capability skip to Section 2.1.5 on page 2-9.<br />
2. Use the catalog number on the front of the Process Control module together with Figures. 2-9,<br />
2-10. and 2-11 to identify the process control capability installed in your unit. For Cat. No.<br />
<strong>360</strong>109, only the channels you have ordered will have switches present on the front of the<br />
module., e.g., 1, 2, 3, or 5.<br />
3. Even if the control logic is simple and obvious, we recommend that you develop a logic<br />
diagram of the process control function.<br />
4. Prepare a specification table which lists the proposed pressure setting, system measurement<br />
point, and relay status for each Process Control channel.<br />
5. Draw a circuit schematic which specifies exactly how each piece of system hardware will be<br />
connected to the Process Control relays.<br />
Do not exceed the relay ratings:<br />
Table 2-1<br />
Relay Ratings.<br />
Relay Configuration<br />
Relay Contact Rating<br />
Relay Contact Type<br />
SPDT (single pole, double throw)<br />
5 A, 60 Vdc resistive load, 30 V rms (42.4 Vpk)<br />
5 A (gold plated for low level switching)<br />
NOTE: If the relay contacts are used to switch high currents, the gold plating may be consumed.<br />
This may make the contacts unsuitable for low level signal switching in the future.<br />
6. Attach a copy of the Process Control circuit diagram to this manual for future reference and<br />
troubleshooting.<br />
7. The required process control connections may be made later. See Section 3.6 on page 3-8.<br />
8. If application assistance is desired, contact a Helix Technology Application Engineer at the<br />
number listed on the title page of this manual.<br />
