2.1.1 Names and functions of various components/specifications
● 24 V power supply terminal (with cover)
A power terminal and a GR (frame ground) terminal, for supplying 24 VDC.
● SECS port
A port for connection to upstream equipment (equipment controller, etc.). Conforms to SECS I/II.
● ID port
A port for connection to a link unit that further connects to an IDRW head.
● Maintenance port (w/ cover)

● POWER indicator
An LED lamp that indicates whether or not the CIDRW controller is powered. It remains lit green when
the controller is powered.
● STATUS indicators
Four indicator lamps (OPERATING, ALARMS, BUSY, ERROR) indicate the current operating status of
the CIDRW controller.
All of these LEDs either remain stably lit or flash immediately after the CIDRW controller is powered
ON or during the initial stage of resetting of the controller
.
OPERATING Green Lights when the state model of CIDRW is OPERATING.
ALARMS Green Lights when "Alarm Status" on the CIDRW is "1" (ALARMS).
BUSY Green Lights when "Operational Status" on the CIDRW is "BUSY".
ERROR Red Lights for 50 ms when a fault is detected (SSACK is not "NO") during service.
Be sure to ground the GR (frame ground) by class D earth work (grounding resistance of
100 Ω or less, diameter of grounding conductor of 1.6 mm or greater).
Otherwise, the CIDRW controller may fail to perform as designed.
