2.3 Connection of ECD Brake BoardBelow 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 relaySIN1 Spare input (not used)

For diagrams of the following terminals refer to see Section 4, Fig.6 & 7.

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.


7/17

Fig. 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.


8/17

Fig. 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.

Fig. 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 1This terminal is currently not used and no wires should be connected.

2.3.7 Brake Coil and Rectifier Connections

The wiring 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 needs to be connected reverse biased at the brake coilfor 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:

Fig. 4

Note: The graph show the sequence of operation from when BK SIGNAL is triggered

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.


11/17

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.




2.4.5 T3

This setting is used to control how fast the voltage will reduce to V1 level after the T2 timeexpires.




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.


The minimum allowed setting is 0ms and the maximum allowed setting is 3000 ms.Default setting is 500ms.

2.5 LED Sequence of OperationFitted to the Brake Board are 3 LEDs which can be used to follow the sequence of operation

of the board. The LEDs are red, green and yellow.

During standby state both the red and yellow LEDs 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 LEDs are illuminated.

During T4 operation no LED is illuminated.

During V1 operation all LEDs are illuminated.

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.
