6.5.3 Chemical Level Switches
The
Easyzon D
has two empty level switch inputs
located on its control panel, see [10] & [11] on
diagrams in section 4.2. They are male 4-pin M12
Code A connections, see diagram below for pin
configuration.
Installation steps:
1.
Check that the pins allocated for the empty
level switch on the lances match up with the
pins on the
Easyzon D
switch inputs (Diagram
below).
2.
Plug the M12 connector from your acid suction
switch into the left-hand side receptacle on the
control panel.
3.
Plug the M12 connector from your chlorite
suction switch into the right-hand side
receptacle on the control panel.
4.
Enable the Acid Empty and Chlorite Empty
alarms in the
Easyzon
software (program 10 &
11 respectively).

state. E.g. A chlorine dioxide gas sensor reaching its
upper limit and activating a relay output.
Installation Steps:
1.
Isolate power to the system.
2.
Select a suitable size cable entry insert from the kit
provided (see section 6.3).
3.
Run the cable from the N.C external alarm
contact through the
Easyzon

4.
Wire into the
Easyzon D
control panel using
the electrical diagram (see section 6.5.2).
5.
Enable the auxiliary alarm option at Program 13 in
the
Easyzon D
software.
✓
Auxiliary alarm installation complete.

REasyzon D
can be inhibited via
external switching if a control process requires it. A
volt free contact is used and is normally closed
in healthy operation.
Installation Steps:
1.
Isolate power to the
Easyzon D
.
2.
Select a suitable size cable entry insert from the
kit provided (see section 6.3).

6.5.7 Gas Sensor
A gas warning device is recommended for use with the
Easyzon D
see your device manual for
instructions. If you wish to use your gas sensing
apparatus to inhibit the
Easyzon D
when an alarm state
occurs, see section 6.5.5.
