Alarm And Error Message System Behavior - Idex Pulsafeeder MPC Vector Installation, Operation & Maintenance Manual

12.2 Alarm and Error Message System Behavior

The following table gives an example of these messages and when you can expect them to be displayed.
Message
FATAL ERRORS: The pump and controller will not run while one of these error conditions exists. The Red LED will
blink and the error message will flash on the screen. Users can access the menu system by pressing the MENU key. The red
LED and the message will cease when the error condition has been corrected.

Displayed When:
The analog input is less than
2.4 mA or greater than 24
mA
The flow meter feedback
signal (Closed Loop
Operation) has fallen below
2.5 ma or is missing.
The tank level monitoring
digital input has triggered
The leak detection
monitoring digital input has
triggered.
The flow detection
monitoring digital input has
triggered. (Only available in
open loop mode)
Internal fault
Communication error exists
between the MPC VECTOR
controller and the AC
DRIVE
Communication error exists
between the MPC VECTOR
controller and the
keypad/display module
Flow has fallen below or not
gone above user defined low
flow threshold for 20
seconds.
Error Clearing/Pump Response
Self-Clearing- Pump motor will stop and remain stopped until
the signal is between 2.4 and 24mA. The pump will resume
speed or flow when the signal is returned.
Self-Clearing – Pump motor will stop, closed loop operation
will cease. Once signal is returned closed loop flow operation
will continue.
Self-Clearing – Pump motor will stop when a tank level input is
activated. When the tank level input is deactivated, the pump
motor will start automatically in remote mode. Manual mode
requires a pump restart (on/off pressed)
Self Clearing/Self-Latching – Pump motor will stop when the
leak detection input is activated. When the leak input is
deactivated, the pump motor will not start and will require a
manual restart.
Not Self-Clearing (Latched) – Pump motor will stop. Pump
may not be restarted until cleared. Pump must return to manual
mode in order to be restarted. (Remote restarts on flow not
detected not allowed)
Not Self-Clearing (Latched) - Pump Motor will stop. Record
AC drive error code on AC drive LED screen and Consult
Factory. Cycle power to attempt to clear fault.
Self-Clearing – Pump motor will stop after 10 seconds of loss of
communications between the controller and AC drive. When
communications are restored the pump will restart.
Not Self-Clearing (Latched) – In Manual Mode the pump will
stop after a 20 second interval if communication is not restored.
In Remote Mode the pump will continue to run when
communications is lost between the keypad and controller.
Not-Self Clearing – Pump motor will stop, closed loop
operation will cease. In manual (local) mode the pump must be
restarted with the on/off key. In remote mode the pump will
keep attempting to restart after each PulsaGuard alarm is
66
recognized.
