To Reset a System Fault!
A system fault must be cleared using the emergency stop button. If the fault is not cleared, the pump will
not be able to start.
5.4
Valve Malfunction
If the solenoids of the pump control valve fail, or if any other event should cause the valve to close without
a normal pump shutdown command, the pump start contacts will open, turning off the pump. A “System
Fault” indicator will display on the screen. A manual reset of the emergency stop switch is required to
clear the fault and restart the pump.
5.5
Normal Stopping of Pump (Local and Remote)
A local pump stop command shall be initiated by pressing the stop pump button or by opening the remote
start contact. By initiating this command the pump control valve solenoid will de-energize and the valve
will start to close. Once the control valve is fully closed, the pump start contacts will open, shutting down
the pump.
5.6
Power Failure
In the event of a power failure, even momentary, it will take approximately one minute for the controller to
boot up. During the boot up process, it shall not be possible to have an automatic pump restart. After the
boot up process has been completed, a normal pump start sequence shall be initiated by using a local or
remote pump start command.
Valve Must be closed to prior to Pump Start!
A local or remote pump start will not be initiated unless the control valve is closed.
