ZERO XDUCER
Signal voltage has fallen too low at transducer: (A) Final discharge, (B) Water
Injection, or (C) Reservoir. This error is usually the result of the transducers
being improperly zeroed. Disconnect the air lines to the transducers and follow
the procedure indicated in the adjustment instructions.
CONTROLS TROUBLESHOOTING GUIDE
The following are recommended service actions. Observe all instructions noted elsewhere in this manual.
All electrical service is to be performed only by a qualified electrician.
Message
Action Needed
No display,
compressor stopped
Check incoming power to the compressor unit. Ensure that the disconnect is
on and that fuses have not blown (or circuit beaker tripped). If power is being
properly supplied to the control box, check the fuses located at the fan starter,
the control transformer fuses, and the fuse located on the AUTO SENTRY W
keypad chassis.
Compressor will not
start
To operate, the controller must be placed into an operating mode (e.g.
AUTO); press the [STOP/RESET] key to put the control into the READY
state, then start by pressing the [START] key. In AUTOMATIC and
SEQUENCE modes, compressors will not start until the pressure drops below
the load pressures.
Display indicates
“NOT BLOWN DOWN”
The controller prevents attempts to start the main motor if the reservoir
pressure is over 5 psig. Pressure continues to be relieved from the reservoir
while this message is on, and the compressor will start automatically after the
pressure has dropped. If this message remains with NO pressure in the
reservoir, follow the transducer zeroing procedure found in the controls
adjustment section.
Display indicates
“REMOTE STOP”
The controller is provided with an input for user-furnished remote controls.
This display indicates that 120 volt is removed from terminal 23 of the
terminal strip. Check all connections of the expansion board, or the
customer-provided controls, if applicable
Display indicates
“SHUTDOWN”
If the display indicates “SHUTDOWN”, refer to the shutdown troubleshooting
section for assistance. In addition to the messages shown, there are several
internal and system diagnostics performed by the controller. Consult the
factory for additional assistance.
