ICE-COP-2 Serial Car Operating Panel Board
The ICE-COP-2 board interfaces between analog devices in the elevator car and serial devices in
the elevator controller. Multiple ICE-COP-2 boards may be “daisy-chained” together to accom-
modate high-rise installations.
Board connection is described in detail on the prints for the specific job.
Normal Operation
During normal operation, I/O LEDs will be lighted when the associated I/O is active (dimmer
when the output is active; brighter when the input is active). The SPA processor LED will be
continuously lighted. If I/O LEDs remain in a static condition or the SPA processor LED is not
continuously on:
• Press the RST button on the board. The I/O LEDs will all cycle and the board will resume
operation.
• Select RS485 communication: DIP switch S2, rocker 8 to the OFF position.
•Input Threshold Level:
• DIP switch S2, rocker 5 OFF = 900mV
• DIP switch S2, rocker 5 ON = 700mV
• Other DIP switch S2 rockers: 1, 2, 3, 4, 6, 7 - OFF (Default).
Board Diagnostics
DIP switches and the I/O status LEDs also provide diagnostic information. When diagnosing
the board, you may:
• Set the two bottom DIP switches (1 and 2) to the ON position.
• I/O 1 and 2 LEDs will flash if RS485 with the cartop is good. LED1 monitors received
data; LED 2 monitors transmitted data. If an LED is not flashing, that phase of com-
munication has failed.
• I/O 4 and 5 LEDs will flash if ICE-EXP-IN port communication with the preceding
board in the chain is good. LED 4 monitors received data; LED 5 monitors transmitted
data. If an LED is not flashing, that phase of communication has failed.
• I/O 7 and 8 LEDs will flash very rapidly (appearing to remain on) if ICE-EXP-OUT
port communication with the next board in the chain is good. LED 7 monitors received
data; LED 8 monitors transmitted data. If an LED is not flashing, that phase of com-
munication has failed.
• Over voltage detection:
• Set all DIP switches OFF:
• LEDs will “scroll” upwards if 33 VDC or greater is detected between V+ and COM.
• Under voltage detection:
• Set all DIP switches OFF:
• LEDs will “scroll” downwards if 18 VDC or less is detected between V+ and COM.
