Timer 3: 'Reset Delay Timer'
Timer 3 controls how long the pump must run before
resetting the 'Lockout Timer' (Timer 1). This allows the
pump to run long enough to re-pressurize the system if
there is pressure loss when not in use. Timer 3 is
factory set to 15 seconds.
To change to the parameters of the internal timers in
the Smart Relay complete the following steps:
1. Turn on the power to the machine and press the
start switch. Remove the front panel and then the
control panel cover. NOTE: Use extreme caution
when reaching into the control box, the
machine has live power. Once powered the
Smart Relay window will display the Default display
screen. (See below)
