Note: For proper operation, both Detergent Signal and Rinse Signal (or pressure
switch) connections must be connected for all installations.
Main Power
Connect Blue and Brown wires to constant voltage source.
Connect Green with Yellow stripe wire to verified earth ground.
NOTICE
If the primary voltage is 440/480 volts, separate, externally mounted
transformers are required (P/N 9230-1022).
Detergent Signal
Connect Yellow and White with Yellow stripe wires to dish machine detergent
power source (or wash pump circuit if no detergent power source connections
are provided).
This is a universal voltage signal input that is capable of accepting any voltage
between 24 to 240VAC, 50/60Hz, or 24VDC. (DC voltage input must observe
polarity; Yellow wire is positive.)
Rinse Signal
Connect Violet and White with Violet stripe wires to dish machine rinse power
source (or rinse solenoid valve circuit if no rinse power source connections are
provided).
This is a universal voltage signal input that is capable of accepting any voltage
between 24 to 240VAC, 50/60Hz, or 24VDC. (DC voltage input must observe
polarity; Violet wire is positive.)
NOTICE
When using the optional pressure switch, the electrical signals from the dish
machine are not used. Disconnect the violet and white/violet stripe wires
from the terminal block.
