Connection to Remote Contacts
The user interface allows speeds "
via remote contact closures (switch or relay). Speed "4"
operates differently than the other three. See Section 2.10,
Remote Closure 4 Behavior.
1.
Turn off all switches and the main breaker that
supplies power to the ePump™.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in the ePump™
electrical circuit before starting the procedure. Failure to
comply may cause a shock hazard resulting in severe
personal injury or death.
2.
Connect one side of the remote contact closure to the
COMMON terminal on J3 REMOTE CONTROL
connector of the controller. See Figure 4.
3.
Connect the other side of the remote contact closure
to INPUT 1, INPUT 2, INPUT 3, or INPUT 4
terminal on J3 REMOTE CONTROL connector of
the controller, depending on which speed is to be
controlled.
4.
Turn on all switches and the main breaker feeding
power to the ePump™.
5.
Verify the operation of the contact closures. If
the correct speed is activated when the closure is
activated, the ePump™ starts, and the message
REMOTE ENABLED appears on the controller
display.
NOTE
When starting the pump via a remote closure, the
pump will first run at the priming speed for the
priming duration, as set by the installer.

Remote Operation
Speeds activated via remote closures always override
speeds that have been activated manually or via an internal
timer program. When the pump is activated via a remote
closure, the keypad is disabled and the message REMOTE
ENABLED appears on the display.

The controller will remain in this state until the contact is
opened. When more than one (1) contact closure occurs, the
highest speed will take priority.
2.10
Remote Closure 4 Behavior
The behavior of speed "4" differs from manual operation
when operated via a remote contact closure. As during manual
operation, the turn-on time of remote closure 4 is immediate,
and occurs at the same time as contact closure (For example,
see Section 2.8). The turn-off time, however, is delayed by 30
minutes.
In other words, when remote closure 4 is de-activated, the
ePump™ will continue to run for 30 minutes, after which
time the controller will turn off the ePump™. The delay may
be manually interrupted by pressing any preset key.
2.10.1
Remote Closure 4 Application -
Booster Pump Support
The behavior of remote closure 4 may be used to allow an
external timeclock fitted with a 20-minute "fireman's switch"
(e.g., Intermatic P/N 156T4042A) to properly control the
ePump™ in conjunction with a booster pump.
Connection for Booster Pump Support:
1.
Turn off all switches and the main breaker that
supplies power to the ePump™.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in the ePump™
electrical circuit before starting the procedure. Failure to
comply may cause a shock hazard resulting in severe
personal injury or death.
2.
Install the normally-closed ¿ reman's switch to the
timeclock assembly. (See timeclock manufacturer's
instructions for details.)
3.
Connect the main timeclock contacts to the booster
pump power input per the booster pump installation
manual.
