PROGRAMMING
INSTRUCTIONS
The 5700/5800 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.
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.

4. Press OK to change the value of Timer-1. Using
the left/right arrow key  or , move the cursor to
the desired field and use the up/down arrow keys
 or  to change this value. See figure 5.
5. Each timer has optional units of time in seconds
(s), minutes (m), and hours (h). To change the
unit of time use the left/right arrow keys  or 
