OPERATING INSTRUCTIONS
11.
Switch on the controller by pressing down the Red ON/OFF Rocker Switch which will
illuminate when switched on.
12.
REB 6, REB 8, REB 10, REB 12 and REB 16 only:- The controller has a boost start function and
when switched on will start the fan running on full speed for approximately 10 seconds.
Thereafter the speed will be determined by the position of the control knob.
13.
Rotating the control knob fully clockwise will increase the speed of the fan from a factory
pre-set minimum to full speed with infinitely variable control.
14.
The minimum speed is pre-set and does not normally need adjusting.
15.
REB 6, REB 8, REB 10, REB 12 and REB 16 only:- The controller has a thermal overload relay
(terminals are designated TP) controlled by thermal protectors in the fan(s). When the fan
thermal protectors trip, (terminals in the fan are also designated TP), the relay switches the
controller off to prevent the fan starting automatically in the event of the thermal
protector(s) cooling and making the circuit again. When this happens the red trip light
switch is illuminated. To reset push the reset button positioned near to the trip light.
16.
IMPORTANT NOTE – REB 1, REB 3 and REB 5 only:- The controller does NOT have a thermal
overload relay and as a consequence the common (U2 – motor live 230V) conductor is
shown on the wiring diagrams routed via the thermal protector(s) in the fan(s) (terminals in
the fan are designated TP). In the event of the thermal protectors overheating, the power to
the motor is cut; however upon the fan sensors cooling then the fan motor can remain live.
To comply with European legislation EN 60335-2-80:2005, when connected to REB 1, REB 3
or REB 5 controllers, in-line duct fans which incorporate self-resetting thermal protectors
must be separately protected from automatic re-start.
TROUBLESHOOTING
17.
If your fan does not start (REB 6, REB 8, REB 10, REB 12 and REB 16 only) –
ensure that the
thermal protection (TP) relay has been correctly wired to the fan thermal sensors.
18.
If your speed controller does not appear to vary the fan speed.
T
he voltage regulation
function can be checked by measuring for a change in Voltage across terminals U1 and U2
with the fan connected. THERE WILL BE NO MEASUREABLE CHANGE IN VOLTAGE IF THE FAN
IS NOT CONNECTED. The fan may be replaced with an alternate load such as a lamp which
will also provide a visual check that there is a variable voltage at the controller output.
19.
To ensure that the fan is operating correctly
.
T
he controller could be temporarily removed
from the system by wiring the fan directly to an isolator. Please note that the wiring will
differ to those diagrams contained herein and that the wiring diagram in the instruction
booklet that was supplied with the fan should be followed instead.
