Operating Instructions

Operating in Low or High Ozone Environments

The controller can operate either low or high ozone
concentration sensor heads by setting the dip-switch on the
controller printed circuit board for the appropriate ozone sensor
head.

Operating as a Controller

The low and high control set points (‘dead band’) are set by
adjusting the two rotary switches as shown in the diagram on the
following page. Both control set points must be operating (i.e. set
to a switch position between 1 and F) for the unit to operate as a
controller.

If either control set point is set in switch position 0, the controller
will operate as a switch (see section “Operating as a Switch” on
page 15).

The ozone concentration set points for each switch position are detailed
in the following table.
