ROLA-CHEM Digital Controller PN 554135 12/26/18 Page: 13 of 24
4.3 Power panel access
4.3.1 Dip switches
The controller has a series of dip switches to control functions that are not normally
accessible on the front panel. These dip switches are located inside the power panel access
cover. To access switches, remove power from the controller and remove power panel
access cover. There are four dip switches- #1 is the top switch. The switch is ‘off’ when in the
left position and ‘on’ in the right position. See appendix for settings.
4.3.2 Fuses
The ORP and pH are independently fused to protect the controller from defective feeders.
These fuses are located inside the lower panel. The fuse holders are shipped with 5 amp
fuses. (Replacement fuses are 5mm x 20mm Fast Acting IEC.)
4.3.3 Flow Switch
The controller has a flow switch terminal located inside the Power Panel Access Cover on
the left side. It is shipped with a jumper in place. The terminal must either have the jumper or
a flow switch installed.
The flow switch light on the face of the controller is also a power light that shows that the
controller is connected to a live power source. If the terminal does not have a closed circuit,
the controller will not turn on.
