External Control Terminals

A pluggable Phoenix screw terminal connector is provided to facilitate additional functionality:

Pin

Signal Name

Function

1

External

Allows control circuit of the brake module to be powered from

 

+24V Supply

an external supply.

 

 

(Eliminates 25ms delay for control power to become

 

 

established from main DC bus power.)

2

Fault

24 volts between this terminal and terminal 9 or 10 indicates

 

 

that the brake module is in a fault condition. This can be used

 

 

for remote fault annunciation.

3

Sync

Connect to same terminal of other brake modules to

 

 

synchronize switching in order to balance brake load between

 

 

two or more modules.

 

 

The 0V pins of synchronized modules must also be connected

 

 

together.

4

Reset

Apply positive pulse between 10V and 24V to remotely reset a

 

 

brake module fault.

5

Fan

The 24-volt DC Fan output is capable of delivering up to 5W of

 

 

power for the addition of an external fan separately mounted

 

 

from the RPM unit. The output becomes active when the heat

 

 

sink temperature exceeds 65° C. Connect between terminals 5

 

 

and 10.

6

Ready

24 Volt output, RPM ready

7

Level

Brake level switching allows the switching voltage turn on

 

 

level to be reduced by as much as 100 volts. The voltage input

 

 

to terminal 7 can be fixed or variable and needs to be connected

 

 

to the 0V circuit common. See FIGURE 1 for a graphic

 

 

representation of the dynamic adjustment capability.

8

I-Lock

Connection point for resistor overheat protection switch.

 

 

Normally-closed switch: Connect between either terminals 8

 

 

and 9 or 8 and 10. Input has a 50 ms filter to reduce noise.

9

0V

Control circuit common.

10

0V

Control circuit common
