Temperature Input (Terminals 7, 8, and 10)
. Follow the appropriate figure below for connecting a temperature
input signal.
Figure 4.4
Figure 4.5
Special Function Input (Terminals 9 and 10).
Input is required to be sourced (powered) from the customer.
Input can be 4-20mA, 0-5V, or 0-10V (refer to Section 4.6 for selection).
External Purge Start (Terminals 11 and 13).
Customer to provide momentary (0.5 to 10 second unpowered) dry
contact to initiate purge cycle.
Input Power (Terminals 14, 15, and 16).
Power required by CAMM must be connected to terminals 15 and 16.
Earth ground should be connected to Terminal 14. When powering multiple units from one power source, polarity
must be maintained.
Purge Interrupt (Terminals 17 and 18).
Customer to provide momentary (0.5 to 10 seconds unpowered) dry
contact to interrupt a purge cycle in progress.
AUTO-purge Purge Valves (SV-1A & SV-1B) (Terminals 21, 22 and 23).
Customer to connect to AUTO-purge
panel. Contacts close upon AUTO-purge cycle initiation, remain closed through the programmed Purge Duration
and open at the start of the After Purge Duration (see Section 5.11).
AUTO-purge Acknowledgment (Terminals 24 and 25).
Acknowledgment contact for customer use. Contacts
close upon AUTO-purge cycle initiation, remain closed through the entire purge cycle (see Section 5.11).
AUTO-purge Main Air Valve (SV2) (Terminals 27 and 28).
Customer to connect terminals 27 and 28 to AUTO-
purge panel.
