Chapter 6: Pump Control
For test purposes you may wish to use hand operated switches to
manually control the pumps and simply watch the system LEDs
to see if the Skymetry WTU-14 is functioning properly. If you are
using "duplex" pump control, select the other output and set it for
Pump Control mode also. After verifying that the unit is function-
ing properly, move your hand-operated pump switches to "Auto"
and verify that the WTU-14 is properly controlling the system.
Output Wiring
The output relays on the Skymetry WTU-14 are for low current
control signals (0.3A 120VAC/1.0A 24VDC maximum).
DO NOT directly connect the power for the pumps to these relays—
THIS WILL PERMANENTLY DAMAGE THE WTU-14.
Use the WTU-14 outputs to control intermediate motor contactors/
relays that will switch actual power to the pumps.
