External Control Terminals
A pluggable Phoenix screw terminal connector is provided to facilitate additional functionality:
Pin Signal Name Function
1 External
+24V Supply Allows control circuit of the brake module to be powered from
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
