DESCRIPTION
1 Fuse
2 4–20 mA differential pressure output GND
+
-
3 Cycling
Remote indication of when a valve is being actuated.
4 Watchdog alarm
Indicates failure of microprocessor.
5 High dP alarm
Indicates that dP has reached the programmed alarm trigger.
6 Service alarm
Indicates that either 100K, 500K, or 950K cycles have been completed.
7 Coil failure alarm
Indicates solenoid failure on the system.
8 Auxiliary alarm
Indicates the alarm state of an auxiliary input device (see 14).
9 Power OK signal
Indicates system power is OK.
10 Isolate valve (for optional tube-cleaner function only)*
11 Purge valve (for optional tube-cleaner function only)*
12 Demand/Continuous switch
Allows remote switching between continuous and demand control modes (when P2 interface
is fitted).
13 Manual cycle
Forces a full cleaning cycle.
14 Auxiliary input
Allows the connection of an auxiliary device (e.g. pressure switch, broken bag detector, etc.).
15 Low header (tank pressure) alarm
Indicates low tank pessure, when connected to an appropriate pressure switch (not supplied).
16 Reset service alarm
Resets the service alarm signal.
17 Reset general alarm
Resets all alarms, with the exception of the service alarm.
Note: The 4–20 mA output (2) is internally powered from the control system. No additional power supply is required.
* The Isolate and Purge functions are disabled on the P-CTX card when attached to the AC/AC baseboard only.
** Isolate and Purge contacts on the AC/AC baseboard have an output voltage equal to mains input voltage (110 V AC or 240 V AC).
