Summary
The control board can be used to generate 0-10V (control voltage - PWM) for multiple fans.
It displays the control voltage value on a legible LCD display.
Depending on the DIP switch settings, the speed of the connected fan can be measured and displayed on the
LCD screens instead.

Connection Details
1. 10V DC Power Supply
2. O/P => 0 -10V Control Signal
3. 0V
4. T => Tacho Signal
Operation
The board is designed to generate a control voltage depending on the potentiometer setting. This can be adjusted
by turning the spindle clockwise for a higher duty cycle PWM signal and vice versa. The range of the PWM is 0-
100% duty cycle which is equivalent to 0-10v. The potentiometer (R4) and spindle are located as seen in
mechanical outline. A DIP Switch (‘T’) on the board enables the user to toggle between control voltage display
and tacho count display. For control voltage display, set the DIP Switch ‘T’ to ON. For tacho count display, set the
same DIP switch to OFF. Only one fan tacho can be monitored or its reading displayed at any one time. To set
the number of pulses per revolution, use DIP switch S0 and Sl. See table below for the various configuration.
Set unused DIP switch S2 to OFF before powering the controller to prevent it entering TEST MODE.

ESD
Many modern electronic components are susceptible to damage from Electro Static Discharge (Static Electricity).
PCB’s which are Static Sensitive should be stored and transported in anti-static packaging until they are required
to be installed. The board must be mounted in an enclosure or cover to prevent access.
Safety
The controller is only suitable for a low voltage (10V DC) supply
Electrical installations should only be carried out by qualified personnel
This appliance is intended to be enclosed in an enclosure which can be accessed by the user during
commissioning.
Transport and Storage
PCBs should be transported in anti static build-up bag or static dissipative bags.
Store in a dry environment
Storage temperature: -30’C to +60’C.
Maintenance and Servicing
There are no user serviceable parts.
