Installation and Operating Instructions

The settings are changed using the upper circuit board's switches
(MODE and DELAY) and potentiometer (SENSITIVITY) and the lower
circuit board's jumpers (Sensor selection and Buzzer). The switches are
displayed in their default setting in the circuit board figure (figure 9).
OPERATING DIRECTION (MODE)
Switch S1 is used to set the operating direction. When the
switch is in its low position, Alarm LED indicator as well as
buzzer is on and relays de-energize when the liquid level is
beneath the trigger level of the sensor (low level mode).
This setting is also used, when an alarm of an oil-layer on
water is required.
When the switch is in its high position the Alarm LED indicator
as well as buzzer will be on and relays de-energize when the
liquid level is above the sensor's trigger level (high level
mode).
OPERATIONAL DELAY SETTING (DELAY)
Switch S2 is used to set the operational delay of the device.
When the switch is in low position relays operate and buzzer
is on after 5 seconds after the level reaches trigger level, if the
level still remains on the same side of the trigger level.
When the switch is in high position, the delay is 30 seconds.
Delays are operational in both directions (energizing, de-
energizing).
Alarm LED follows the sensor current value and trigger level
without delay. Fault LED has a fixed delay of 5 sec.
TRIGGER LEVEL SETTING (SENSITIVITY)
Trigger level setting is executed as follows:
1. Immerse the sensor's sensing element to the
