ESD
Many modern electronic components are susceptible to damage from Electro Static Discharge (Static Electricity).
During commissioning, avoid unnecessary contact with electronic components on PCB’s.
PCB’s which are Static Sensitive should be stored in anti-static packaging until installed.
Installation
General:
See “Safety” information above.
For connections, see Connection Details table above. Route control wiring separately from AC mains wiring.
Remove enclosure knock-outs as required to fit cable glands, taking care not to damage the PCB. Cable entry at
enclosure end is recommended.
Tools:
A 2.5mm flat screwdriver is recommended for the screw terminal block clamps and Variable Resistor adjustment.
A voltmeter is required during commissioning.
230VAC Supply:
Controller connection to 230VAC supply must be fused to 13A maximum.
The supply for single phase fans up to 13A total load may be connected via this control PCB, connect Fans to
230VAC output and Earth output terminals. For higher currents or 3-phase fans route supply direct to fans.
Fans:
Connect fan supply, speed control and tachometer leads, see table above for connections. If fan has a 10V
output wire cut back & insulate. If fans are Alarm Relay type (not Tachometer), connect Fan N/C & COM between
tachometer Input and 0V. If fan monitoring is not required, then link tachometer Input to 0V to prevent alarms.
Select Inputs:
Connect Run/Stop and Speed/Set-point select inputs as required for the application, see Tables below.
PC Switches and Variable Resistors:
Set DIP Switches and Variable Resistors as required, see tables and procedures below.

Operation
Fan Speed Control and LED’s:
1) Stop/Run: Fans will not run unless both Run enable signals (Switched Live and Volt Free) are present.
LED “En” will be illuminated if Fan Run is enabled, and will flash mostly off if not. Unit is shipped with
both Run enables linked. “En” LED Off indicates either no 230VAC supply or a PCB fault.
2) High Speed: Fans will run at High speed if any High Speed signal (Switched Live or Volt Free) is active,
LED “B” illuminated. If the “High” potentiometer set speed is lower than the “Low” potentiometer set
speed the fan will continue at the “Low” set speed.
3) High Speed Delay Start: Enabled by DIP Switch. Fan Speed Outputs will remain at Low speed after the
High Speed Input becomes active, for this timer period. (exception - BMS input responds immediately) If
High Speed Delay timer is running LED “B” will flash, mostly Off.
4) High Speed Run-on: Fan Speed Outputs will remain at High speed after the “High Speed” input ceases
to be active, for a period set by R3. (exception - BMS input responds immediately) If Run-on timer is
running LED “B” will flash, mostly On.
Fan Monitor:
1) “FAN1” and “FAN2” LEDS, Green LED = Fan Running, Red LED = Fan Alarm
2) Alarm Relay output: Contacts closed = No Alarm, Contacts Open = Fan Alarm or Power Fail.

Duty Sharing (Alternate Fan Run)
The controller will run each fan alternately.
Each fan will run for a period selected by the DIP Switch setting, see table.
In the event of a fan alarm (detected by controller monitoring the Fan Relay / Tachometer signal) the controller
will:
1) Automatically switch over to the alternate fan
2) Indicate the Fan Alarm by means of the Fan red LED and Alarm Relay
Note: at the end of each Duty Share period the controller will select the alternate fan. If the alternate fan is faulty
the controller will swap back.
Simultaneous Fan Run (Load Share)
In this mode, for settings above the equivalent of two fans on minimum speed, both fans will run and the load will
be shared. For speed settings below this the fans will run alternately to allow the maximum airflow range.
In the event of a Fan Alarm the remaining fan speed will be doubled (up to full speed) to compensate, or for low
speed setting the alternate fan will run.
Single Fan operation
For single fan operation connect the fan to Fan 1 controller terminals. Set the DIP switch for Single Fan operation
to suppress alarms from the unfitted fan.
Power-up Check
At power-up all LED’s will illuminate and Alarm Relay energise for a few seconds. If only one fan is running the
controller will run Fan 1 briefly to check it is operating correctly, then switch to Fan 2 to check that fan. Fan run
check inhibited if Enable not active.
Maintenance and Servicing
The PCB has no replaceable parts, if a fault develops return the PCB to the manufacturer.
Terminal lock Use
The terminal blocks fitted are operated as follows:
Insert a 2.5mm or 3mm flat blade screwdriver fully into the upper hole as shown, to open the terminal wire entry.
Insert the wire into the lower hole, then remove the screwdriver to leave the wire clamped in the terminal.
Alternatively, open the wire entry by inserting the screwdriver fully from the opposite side of the connector as
shown
Insert the wire into the lower hole, then remove the screwdriver to leave the wire clamped in the terminal.
Check wire clamp has moved clear
to
allow wire entry
