5.1.8 PCA INDICATOR
The PCA indicator will illuminate if the Program Card is absent or not properly seated. A
manual Reset is required after the program card is properly seated. If the unit is in the
Diagnostic Display mode, the PCA indicator will flash ON (once, twice, or three times) to
indicate the fault event number being displayed. See Section 2.18.
If the unit is in the Configuration Change Fault mode, the PCA indicator will flash at a 4 Hz
rate. See Section 2.11.
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 2.6.
5.1.11 COMM INDICATOR
The COMM indicator will illuminate for a period of 50 ms when a valid frame is received on
the communication 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 (210E / 2010)
During normal operation the 210E / 2010 model Channel Status indicators will display all
active proceed signals (Green or Yellow).
In the fault mode the Channel Status indicators will display all proceed signals active at the
time of a 24VDC fault (VDC FAILED), or Watchdog fault (WDT ERROR). In the event of a
Conflict, Red Failure, Dual Indication, or Clearance fault only the channels on which the fault
occurred will be displayed.
5.1.13 CHANNEL STATUS INDICATORS (210ECL / 2010ECL / 2018ECL)
During normal operation the
“ECL” 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 2.19) with the field
status.
5.2 FRONT PANEL CONTROLS
5.2.1 RESET BUTTON
Depressing the Reset button resets the Signal Monitor 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 Sections 2.18 and 2.19.
