GUIDE TO CONTROLS:
Below is a listing and the location of the different components for the controller:
Standard Version (Non-CE)
CE Version (ex. AZ23-4223-CE)
1.
Power indicator:
This green LED lights when AC power is ON.
2.
Relay indicator:
This red LED will light whenever the controller energizes the relay, in response to the
proper condition at the sensor input(s) and after the time delay.
3.
AC Power terminals:
Connection of 120 VAC power to the controller. The setting may be changed to
240 VAC if desired. This requires changing internal jumpers; this is covered in the Installation section
of the manual. Polarity (neutral and hot) does not matter.
4.
Relay terminals (NC, C, NO):
Connect the device you wish to control (pump, alarm etc.) to these
terminals: supply to the COM terminal, and the device to the NO or NC terminal as required. The
switched device should be a non inductive load of not more than 16 amps; for reactive loads the current
must be derated or protection circuits used. When the red LED is ON and the relay is in the energized
state, the NO terminal will be closed and the NC terminal will be open.
5.
Invert switch:
This DIP switch reverses the logic of the relay control in response to the sensor(s):
conditions that used to energize the relay will make it turn off and vice versa.
6.
Latch switch:
This DIP switch determines how the relay will be energized in response to the two
sensor inputs. When LATCH is OFF, the relay responds to sensor Input 1A only; when LATCH is ON,
the relay will energize or de-energize only when both sensors (1Aand 1B) are in the same condition
(wet or dry). The relay will remain latched until both sensors change states.
7.
Time Delay:
After the input(s) change(s) state, this control sets a delay from 0.15 to 60 seconds
before the relay will respond.
8.
Input 1Aand 1B indicator:
These amber LEDs will light immediately whenever the appropriate sensor
attached to the terminals detects liquid, and will turn off when it is dry.
9. Input
terminals:
Connect the wiring from the sensors to these terminals: A to the upper pair, B (LC11
Series only) to the lower pair. Note the polarity: (+) is a 13.5 VDC, 27 mA power supply (to be
connected to the red wire of a Flowline sensor), and (-) is the return path from the sensor (to be
connected to the black wire of a Flowline sensor). If polarity is reversed, the sensors will not work.
