Programming Instructions
The 900/1400 can be configured to run in Time Delay
or Auto Start/Stop with lockout. Machines are factory
set with Auto Start/Stop with 4 hour Lockout. A Smart
Relay controls how the machine will operate by using
three internal timers; these timers are adjustable. The
following is a brief description of these timers:
Timer 1: 'Lockout Timer' (Time Delay)
Timer 1 de-energizes (lockout) the machine if not being
used for a preset time. If machine has ‘Locked out’ it
can only be re-energize by pressing the ‘Pump On’
switch. Timer 1 is factory set to 4 hours.
Timer 2: 'Auto Start/Stop Timer'
Timer 2 allows the pump to run in bypass for a preset
time. If the pump runs in bypass longer than the allotted
time the timer will drop power to the motor contactor
and machine will be in standby mode. Squeezing the
gun trigger will restart the pump (if Timer 1 has not
locked out). Timer 2 is factory set to 30 seconds.
