System Status Indicator LEDs
The Model 133 Monitor has two LEDs that show the operational status of
the Control System. The control has two basic operating modes:
AUTO Mode
A green LED is lit whenever the Control is in the AUTO mode of
operation.
This means the automatic control of the replenisher pump(s) is governed
by the Model 131 Control. During this operating mode, the red PUMP
light
will turn on and off periodically as the pump(s) are switched on and
off
by the control.
MANUAL Mode
The green LED is off in this mode. However, the red PUMP LED is always
on. In Manual mode, the replenisher pump(s) are continuously powered
through
the Model 120 Power Module unit, and the operator is responsible for
switching
the power.
