The water slip alarm option is a secondary board that is mounted on the main control
board. This board has two inputs and three outputs per channel. The first input,
which comes from the main control board, is the ready input. The second input,
which comes from the water slip sensor, is the water slip input. The first output,
which is fed back to the main control board, controls the ready and water slip
LED(s). The second output is a 1/4 amp SPST form A dry contact relay. This relay
is used for computer sensing and is NOT intended for the controlling of electrical
loads. The third output is a 6-amp DPST form C dry contact relay. This relay can be
used for sample pump or other heavier electrical load control. This relay output
terminal is normally wired for a 120VAC sample pump (ground, neutral, and line). If
there is water carry over (water slip LED), computer sense and load control relays
will be turned off. If the temperature of the cooler rises above 10

°

C (50

°

F), the ready

LED, computer sense and load control relays will be turned off. This means that the
relays operate in a fail-safe manner.

Note: If the alarm relay/water slip option is not installed, the SLIP LED(s) on the
front of the cooler will be off.
