Jumper Settings for Unused
Stations
CAUTION:
To prevent
pump
damage when using
a pump start relay, use a jumper to connect un-
used stations to a station that is being used. If pro-
gram information is lost during a prolonged power
outage, the ESP will automatically run a "default"
program when power is restored. This program
runs all stations for 10 minutes. If unused stations
are not jumpered, the pump will operate with no
flow (dead-head) during this 10-minute period.
Dead-heading may cause the pump to overheat or
burn out.
Connect Transformer
The ESP controller has a nipple-mounted trans-
former that provides a 1/2" nipple below the cabinet.
Use this nipple to connect the ESP to an electrical
function box or other code-approved enclosure for
wire connections.
Œ
Make sure the 117-Volt AC power is off.
•
Connect the white wire from the controller nipple
to the white wire coming out of the electrical con-
duit from the power source. Make sure all connec-
tions are made with code-approved insulated con-
nectors.
Ž
In the same way, make the black-to-black and
green-to-green wire connections.
•
Close up the weatherproof junction box after all
connections are complete.
