Installing Brake Monitoring

Brake monitoring via an independent contact is required by code only for disc brakes. A spare
iBox input (SP2D), or a programmable input (Brake Switch) on an ICE-MIAC board, may be
used for the brake contact. The brake monitoring contact may be provided as part of the brake
assembly. If not, a micro-switch (rated for at least 1/4 Amp, 125VDC) must be provided by the
installer and mounted such that when the brake picks, the switch activates (see note below).
Refer to job prints for electrical connection information.
The brake monitoring contact provides a path between the iBox 110VDC (#3) bus and the SP2D
or Brake Switch input. If the brake fails to pick (or drop) at the proper time, this signal will
cause the controller to generate a Brake Pick Fault
FAULT" on page
page 6-15). The fault message is shown on the iBox LCD display, on the iView Operational Sta-
tus tab and in the iView Event Log.
Note
On the iView > Controller > Configuration
> Brake > Control tab, switch parameters
are provided to specify the polarity of the
SP2D/Brake Switch input (active high or
low). In addition, parameters direct the
system to monitor for a brake pick and/or
brake drop fault. If neither pick or drop
monitoring are checked, the controller will
ignore the SP2D/Brake Switch input.
Danger
When installing the switch, take all necessary precautions not to interfere with normal
brake design or operation.
