3.0 Modes of Operation
The Series 130 can operate either as a controller or an alarm switch.
These modes control the two on-board relays in different ways. The
required operating mode is selected via dipswitches as outlined
below.
3.1 Warm up
Warm up the controller to burn off contaminants on the
sensor.
During warm up the LED will flash green slowly. If the
controller has not been run for a few days it may take an hour or
two to reach full accuracy.
3.2 Operating in Low or High Ozone Environments
The controller can operate either low or high ozone concentration
sensor heads by setting the dip-switch B-1 to the “off” position for
a low concentration head and “on” for a high concentration head.

3.3 Operating as a Controller
Set the mode dip switch (B-2) to position "off". Set the low (“C”)
and high (“A”) control limits [‘dead band’] by configuring the dip
switches as per the dip switch table on page 8. When in control
mode relay 1 operates as per the table and diagram below. Relay
2 is opposite.
