 Elevator controllers and other electrical components can cause serious harm or
death if installation guides are not met. It is the responsibility of the installer of our
equipment to ensure that once installed, the equipment does not pose any threat,
danger or hazard.
Section 1.2 Obligations & Liability
1.2.1 Following operating instructions.
 In order to ensure safe handling and problem free operation of this
equipment, it is absolutely essential for the relevant personal to be fully
acquainted with the relevant safety regulations.
 These operating instructions contain the most important information for
operating the equipment correctly and safely.

2.1 Product Overview
The brake board is specifically designed to control elevator machine brakes across a wide
range of voltages and loads. It may also be used to control door lock cams to ensure smooth
and quiet cam operation.
The following user adjustable parameters ensures smooth and quiet brake operation and
reduction of back EMF surges;
 Brake lift time and voltage
 Brake cooling time and voltage. (reduced holding voltage once brake has lifted)
 Brake drop time
2.2 Contents of the Brake Board Kit.
1 brake board
1 ferrite core for 24VDC supply
1 1000v 35A bridge rectifier
4 crimp lugs for rectifier
1 power diode for brake coil back EMF protection
1 system manual
2.3 Connection of ECD Brake Board
Below is a list of the connection terminals on the brake board.
24VDC Brake board power supply
BKSIGNAL Brake lift input
AC SUPPLY Brake coil supply AC voltage only. Min 80VAC. Max 240VAC.
VAC BRAKE Brake coil connection
NO NC C Loss of AC output relay
SIN1 Spare input (not used)
For diagrams of the following terminals refer to see Section 4, Fig.7 & 8.
2.3.1 24VDC
The 24VDC input is the power supply to the microprocessor and as such should be as stable as
possible.
Supplied in the kit is a ferrite core that is to be installed on the 24Vdc supply. The wires for
this supply should be twisted together then looped once through the ferrite core (see fig.1).
Note this is particularly important if the board is being supplied from a switch mode power
supply.

7
Figure 1
2.3.2 BKSIGNAL
The BKSIGNAL input is the signal from the lift controller to initiate the brake lift sequence.
This input only requires a voltage free contact.
2.3.3 AC SUPPLY
The AC SUPPLY terminal is used for the AC voltage @ 50Hz for the brake board.
This voltage is regulated by the brake board and output from terminal VAC BRAKE to control
the brake
Important Note: This voltage cannot exceed 240Vac and must be @ 50Hz
2.3.4 VAC BRAKE
The VAC BRAKE terminal is the AC output from the Brake Board to the Brake coil.
As a DC voltage is required for most brake coils, use the supplied rectifier on this output.
2.3.5 NO NC C
The NO NC C relay contacts are used to signal to the lift controller that a fault has occurred
with the brake board, inhibiting any further lift operation. See example Section 4, Fig. 6 & 7,
where the relay C & NO contacts are used for the controller PRV (prove) input.
When the brake board is functioning normally, the fault relay will be energized.
When any of the faults listed below are detected the fault relay will drop out:
 Loss of AC SUPPLY. “Loss of AC!” will be displayed on the LCD. (No AC voltage at
AC SUPPLY, Fig. 2). Brake board will remain inoperative until AC SUPPLY restored.

8
Figure 2
 Loss of 24VDC
 Triac shorted. “Triac damaged!” will be displayed on the LCD. (Fault detected with
Triac, Fig. 3).
This fault is a fatal error and requires a 24VDC reset. Note: If a triac fault is detected
while the brake board is operating, the brake board will finish the run and set the Triac
damaged fault when BK SIGNAL turns off.
Figure 3
The relay contacts are rated as follows:
Max Voltage: 125 VAC or 60VDC
Max Current: 0.5A
Note: This relay is not rated for use in the Safety Circuit of most elevator controllers. If the
intend use of relay C and NO contacts is to open the Safety Circuit then an appropriately rated
slave relay must be used.
2.3.6 SIN 1
This terminal is currently not used and no wires should be connected.

9
2.3.7 Brake Coil and Rectifier Connections
The wiring current rating from the VAC BRAKE output to the rectifier and brake should be
sized according to the load of the brake coil.
The supplied power diode shall to be connected reverse biased at the brake coil for back EMF
suppression.

2.4 Setup of Brake Board
The Brake Board has 6 adjustable parameters which can be adjusted to optimize the operation of
the brake:
Vmax, V1, T1, T2, T3, T4.
T2 T3 T4
V1
Vmax
T1
Note: The graph show the sequence of operation from when BK SIGNAL is triggered
Figure 5
2.4.1 Vmax Adjustment
Vmax is used to set the maximum AC voltage output (VAC BRAKE) and is expressed as a
percentage value of the input voltage (AC SUPPLY)
Vmax is a code protected user adjustable setting. To adjust this setting, first go to LCK and set
to 6789.
E.g.1. Set to 50% if AC SUPPLY is 240VAC and you require 120VAC at VAC BRAKE.
E.g.2. Set to 100% if AC SUPPLY is 240VAC and you require 240VAC at VAC BRAKE.
The Brake Board is shipped with Vmax set at a default value of 35%. The minimum allowed
setting is 10% and the maximum setting is 100%.
After any adjustments to Vmax, it is recommended that LCK be changed to any value other
than 6789, so as to prevent an accidental vmax parameter change, which may cause an over
voltage supply to the brake coil.
2.4.2 V1 Adjustment
V1 is the holding voltage for the brake coil and is adjustable to a percentage of the input
voltage at the AC SUPPLY terminal; it is also interlocked to the Vmax setting so that it cannot
be set to a higher value than Vmax. The minimum allowed setting is 10% and the maximum
setting is 100% or Vmax whichever is the lesser.
The Brake Board is shipped with V1 set at a default value of 25%.
Once the lift is running this value can be adjusted either up or down to give the desired brake
hold voltage and thus cooling effect.

11
2.4.3 T1
This setting is used to control how fast the brake coil will get to full voltage (v max).
It is adjustable in steps of 50 ms.
The minimum allowed setting is 100ms and the maximum allowed setting is 5000 ms.
Default setting is 500ms.
2.4.4 T2
This setting is used to control how long the brake coil will stay at full voltage.
It is adjustable in steps of 50 ms.
The minimum allowed setting is 100ms and the maximum allowed setting is 5000 ms.
Default setting is 1500ms.
2.4.5 T3
This setting is used to control how fast the voltage will reduce to V1 level after the T2 time
expires.
It is adjustable in steps of 50 ms.
The minimum allowed setting is 100ms and the maximum allowed setting is 5000 ms.
Default setting is 500ms.
2.4.6 T4
This setting is used to set how fast the brake voltage will reduce to 0v after the BK SIGNAL is
switched off.
It is adjustable in steps of 50 ms.
The minimum allowed setting is 0ms and the maximum allowed setting is 3000 ms.
Default setting is 500ms.

12
2.5 LED Sequence of Operation
Fitted to the Brake Board are 3 LED’s which can be used to follow the sequence of operation
of the board. The LED’s are red, green and yellow.
During standby state both the red and yellow LED’s are illuminated.
During T1 operation only the red LED is illuminated.
During T2 operation only the green LED is illuminated.
During T3 operation the red and green LED’s are illuminated.
During T4 operation no LED is illuminated.
During V1 operation all LED’s are illuminated.

The graph shows the LED sequence of operation from when BK SIGNAL is triggered
Flashing yellow LED indicates the brake board is in the following fault state;
 Loss of AC SUPPLY. “Loss of AC!” will be displayed on the LCD. (No AC voltage at
AC SUPPLY). Brake board will remain inoperative until AC SUPPLY restored.
Flashing red LED and illuminated yellow LED indicates the brake board is in the following
fault state:
 Triac shorted. “Triac damaged!” will be displayed on the LCD. (Fault detected with
Triac). This fault is a fatal error and requires a 24VDC reset. Note: If a triac fault is
detected while the brake board is operating, the brake board will finish the run and set
the Triac damaged fault when BK SIGNAL turns off.
