Supply relay 1 controls terminals 1 and 2. Figure 36
shows the jumper wire from terminal 13 (L1
220 VAC)
to all other even pins (i.e., 2, 4, 6…). This applies L1
(
220 VAC) to terminal 2. When supply 4 on the WE-8
is programmed, this will close supply relay 1 and
apply L1 (
220 VAC) through pin 2 to pin 1. This signal
is used from the terminal to the chemical supply
vendors first pump.
IMPORTANT: Supply 4 must be programmed on
the WE-8 to create the signal on terminal 1. The
chemical vendor will always use terminal 14 as the
common terminal for all pumps. This will apply for
the remainder of the 220 VAC circuit for each of
the pump signals. For the remainder of the relays,
supply relay 2 will control terminals 3 and 4;
supply relay 3 will control terminals 5 and 6; etc.
IMPORTANT: The WE-8 must be programmed
for supply 4-9 to energize the supply relays 1-6
respectively.

The 220V can be transformed to other values to drive
other type supply pumps.

Also, pumps with different operating voltage
requirements can be combined.
