1.1 The control system allows for intelligent pump control
while improving system reliability. Timers and relays
used in a conventional controller are integrated into a
single sequence controller. The working program is
stored on a non-volatile EEPROM chip that is an inte-
gral part of the unit. This means there is no danger of
ever losing a program due to power losses.
1.2. OK LED is on when the processor is running. If this
LED is not lit, check power connections. If power is
applied to the unit and LED is still not lit, replace unit.
1.3. The Aux in LED is reserved for future use.
1.4. The Flow Sw. LED is lit when the flow switch is
closed.
1.5. The Pressure LED is lit when the pressure switch is
closed.
1.6. The Out3 LED is lit when Output 3 is closed. Output
3 is closed when the pressure switch is closed, or
when the pressure switch is open and the run timer is
active.
1.7. The Out2 LED is lit when Output 2 is closed. Output
2 is closed when the flow switch is closed.
1.8. The Contactor LED is lit when the Contactor output is
closed. The Contactor output closes when the pres-
sure switch is closed, or when the pressure switch is
open and the run timer is active.
2.0 CHANGING THE MINIMUM RUN TIME
2.1 Adjustable Settings
2.2 The run timer is adjustable to 15 seconds, 30 sec-
onds, 1 minute, 2 minutes, 3 minutes, 4 minutes, and
5 minutes. On the right hand side of the PCB near
the OK LED is a small black plastic jumper which sets
the run time. Shorting the pins at the top of the con-
nector will set the run time to 5 minutes. Shorting the
next set of pins down will set the timer to 4 minutes.
Shorting the bottom set of pins sets the timer to 15
seconds. Each setting is labeled on the PCB. If no
jumper is used, the timer defaults to 15 seconds.
