Table 6.12 ICE-IRB Relay Board
Signal (Left Edge)
Signal (Right Edge)
BD:
Brake Driver relay indicator. When the BD relay on
the Relay board is closed to pick the brake, this LED
will light. Monitored by Safety Processor A.
M1:
Drive contactor coil connection.
TB:
Brake Triac active indicator. When the brake triac
on the Relay board is active (completes circuit for BD
relay), this LED will light. Monitored by Safety Proces-
sor B.
M2:
Drive contactor coil connection.
BRD:
Brake Redundancy. This LED lights when the
main brake contactor drops out.
MR:
Connects to drive contactor auxiliary contact
for redundancy input.
BDRD:
Brake Drive Redundancy. This LED lights when
the BD relay drops out.
MX:
Connects to drive contactor auxiliary contact
for brake qualification.
MD:
Motor Drive relay indicator. When the MD relay on
the Relay board is closed to enable the motor, this LED
will light. Monitored by Safety Processor A.
M:
Part of MX circuit.
TM:
Motor Triac active indicator. When the motor triac
on the Relay board is active (completes circuit for MD
relay), this LED will light. Monitored by Safety Proces-
sor B.
UP:
Up direction output to MCE System 12 SCR
Drive.
MRD:
Motor Redundancy. This LED lights when the
main motor contactor drops out.
DN:
Down direction output to MCE System 12
SCR Drive.
MDRD:
Motor Drive Redundancy. This LED lights when
the MD relay drops out.
_ _:
Not connected.
SAFC:
Safety Cartop input. Cartop safety relays and
switches are wired in series between SAFH (Safety
Hoistway) and SAFC. If any contact in the safety string
opens, there will be 0VDC on this input and the car will
not run. If all safety contacts in the string are closed,
there will be 110VDC on this input.
2D:
120VAC power to the drive. Fused on IRB
board (fuse F2D).
SAFH:
Safety Hoistway input. Hoistway safety relays
and switches are wired in series between the #3 bus
and SAFH. The patch also includes the Governor
switch, with the GOV connection providing access to
the #3 bus via the governor switch. (#3 to GOV
through governor switch, GOV to SAFH through hoist-
way safety relays and switches). The job prints for the
job provide specific wiring instructions. If any contact
in the safety string opens, there will be 0VDC on this
input and the car will not run. If all safety contacts in
the string are closed, there will be 110VDC on this
input.
1D:
System common to the drive - source is the
1 bus.
SP1 D
: Optional input. See job prints.
BK2:
Connects to the brake contactor for redun-
dancy checking. The source of power for this cir-
cuit comes from fuse F2 on the IRB board.
SP2 D
: Optional input. See job prints. (When used as
a brake pick switch input: Set brake = 110VDC. Picked
brake = 0VDC.
BK1:
Connects to the brake contactor for redun-
dancy checking. The source of power for this cir-
cuit comes from fuse F2 on the IRB board.
SP2:
Optional input. See job prints.
BC1:
Connects to the brake contactor coil (see
job prints for connection).
SP3:
Optional input. See job prints.
BC2:
Connects to the brake contactor coil (see
job prints for connection).
