Rola-Chem 554230 ORP Digital Controller - Manual (Page 9)

4.0 Operation
4.1 Startup
Do not add chemicals to the feeders until all
start-up operations are completed. Using
a DPD test kit, manually adjust and balance the pool to acceptable ranges.
Automation should be used to maintain
chemical levels, not to balance a pool that is
out of acceptable ranges. With the controller in the OFF Mode, turn the filter pump
on and check for leaks in the system and flow through the flow cell. The flow lamp
will be illuminated if the controller has power, it is connected to the flow switch and
there is adequate flow. If a flow switch is not attached, the flow lamp will be
illuminated if there is a jumper in the flow cell terminal. It is recommended that a
flow switch always be used.
4.2 ORP setting
Press and release the controller MODE button until the AUTO light is off. Then
select the desired set level and feed time cycle.
4.3 Operating mode
Press the MODE button until “AUTO” is lighted. This is the operational mode for the
controller. The controller must be in this mode to maintain the desired parameters.
Timed feed settings: T
he feed lamp will flash during the feed time and be constant
during the delay time of the feed cycle. Feed lamp will be active until set-point is
reached and feed cycle is completed. If over feeding is occurring, consider shorter
feed cycle.
Constant feed setting: T
he feed lamp will flash while feeding. Power will be supplied
to feeder until set-point is reached.
The feed lamp will not activate when the alert lamp is on (ORP below or above the
alert settings).
Low feed rates can cause the feeder to lag or feeding to be extended. A high feed rate
can result in too much chemical being added.
