Timer Setup
Connect the Battery to the POWER terminals, and connect the Pump to the MOTOR terminals.
If using a temperature probe, it may be connected at any time. If a probe is connected temperature
control will be active. If no probe is connected, temperature control is not used.
Battery voltage must be above 10 volts for operation. The display will switch to the battery display when
the battery gets too low for pump operation. Lob will flash on the display along with the voltage and
temperature, to indicate the voltage is too low for operation.
A Plug-In Terminal Block is used for connection to Modbus and/or the Remote Inhibit input.
A dry contact connected to the Input will inhibit pump operation when closed and this will be indicated
by INH being displayed when pump operation is inhibited.
Other Operation Features and Information
Plugging in the external temperature probe will activate temperature control in the CpM and On-Off
modes. When in Modbus mode of operation you must have probe connected for Modbus to have the
ability to enable/disable temperature operation. If Modbus enables temperature control, it will not be
active or show the status of being active until a probe is connected. If no external probe is connected
(shutoff with temperature is disabled) the Temperature ON and Temperature OFF display selections will
display a period (.) in the ones digit, no period is shown if the probe is connected.
Voltage cut back is always enabled in the CpM mode of operation but is not enabled for Modbus or
ON/Off control. If the timer is in actual voltage cut back there will be a period under the c (cycles
selection on the display) to indicate cutback due to low voltage. If the unit is operating normally the
period will not be seen.
Battery voltage is accurate to a couple of tenths. So use a voltage meter to verify when you need
accuracy.
Some fuses maybe hard to remove or install, grabbing the fuse with pliers and slowly rocking the fuse
back and forth will make it easier to remove and install.
While in Shutdown (Sdn on display) you may have to hold the switch down about 1 sec to get display
back on for it to change to the next display selection.
The Duration (On) cycle is run first after Power On Reset.
The display will blank after a time out period, but one of the LEDs will be On. If the display is blank, press
the rotary knob quickly and the display will come back on.
Always power off timer prior to any work on pump.
