5.1.9 DIAGNOSTIC INDICATOR
The DIAGNOSTIC indicator will illuminate when an internal hardware or firmware test
function has failed. This indicator is intended to inform the service technician of a monitor
hardware or firmware failure. Due to the nature of these hardware or firmware failures,
other fault indicators that may be concurrently illuminated may not be valid for trouble
shooting purposes.
5.1.10 RP DETECT INDICATOR
The RP DETECT indicator will illuminate when the Recurrent Pulse detection function has
triggered a Conflict, Dual Indication, or Red Fail fault. See Section 2.7.
5.1.11 COMM INDICATOR
The COMM indicator will illuminate for a period of 50 ms when a valid ECcom frame is
received on the EIA-232 port or Ethernet port. The COMM indicator will flash at a 4 Hz rate
if the port is disabled due to the DTR signal in the false state while a frame is in the transmit
queue.
5.1.12 CHANNEL STATUS INDICATORS
During normal operation the 2018KCL model Channel Status indicators will display all
active signals (Green, Yellow, and Red).
In the fault mode the Channel Status indicators will display all signals active at the time of a
fault. In the event of a Conflict, Red Failure, Dual Indication, or Clearance fault the
channels on which the fault occurred will be displayed alternately (see Section 2.18) with
the field status.
5.2 FRONT PANEL CONTROLS
5.2.1 RESET BUTTON
Depressing the Reset button resets the 2018KCL after it has been triggered by a fault. The
monitor will remain in the reset mode only if the fault condition has been restored to normal.
In the event of a monitor hardware or firmware fault (DIAGNOSTIC) the Reset button may
not reset the monitor. A power-up restart may be required.
The Reset button also provides control of the Diagnostic Display mode. For a complete
description of Diagnostic Display operation see Section 2.18.
5.3 RED INTERFACE CONNECTOR (P1)
This connector provides the required inputs for the 2018KCL to monitor the Red Field
Signal outputs. It is polarized to insure proper mating with the adapter cable. Ejector
latches are included to facilitate removal and prevents the cable from inadvertently
disconnecting.
The 2018KCL will function as a standard 210 Signal Monitor when the
cable is disconnected.
