DIAGNOSTIC OPTIONS
Viewing Event Counters
Menu 2 contains a series of counters that increment automatically in response to various
events. These counters can be used to troubleshoot issues with a particular installation. Each
counter will count to a maximum of 1000 and then will stop incrementing. At the bottom of
Menu 2 is an option to clear these counters. Clearing the counters also clears the event log.
1. ESDs: Increments each time the system shuts down as
a result of the ESD Contact opening, the High Temp ESD
Setpoint being exceeded by either Process Temp or Aux Temp
(if enabled), or a high or low voltage alarm.
2. Flame Fails: Increments each time the system shuts down as
a result of failing to ignite the pilot within the allocated number
of retries.
3. High Pressure ESDs: Increments each time the system shuts
down as a result of the High Pressure Contact opening or
the 4-20 Pressure reading exceeding the 4-20 High Pressure
Setpoint.
4. Level ESDs: Increments each time the system shuts down as
a result of the Level Contact opening or the 4-20 Level reading
dropping below the 4-20 Low Level Setpoint.
5. Low Pressure ESDs: Increments each time the system shuts
down as a result of the Low Pressure Contact opening or the
4-20 Pressure reading dropping below the 4-20 Low Pressure
Setpoint.
6. Thermocouple Errors: Increments each time the system shuts
down as a result of a thermocouple issue such as a short
circuit, open circuit, or ground short.
7. Relights: Increments each time the system attempts to
automatically re-ignite the pilot. The first ignition attempt after
a manual start is not counted.
8. Resets: Increments each time the door card is reset by a
power loss or by manually pressing the reset button.
9. System Errors: Increments each time the system shuts down
as a result of an internal system error.
10. Terminal Card Errors: Increments each time the system shuts
down as a result of a terminal card error.
Viewing the Event Log
The Event Log can be accessed from the end of Menu 2. The log contains entries for various
types of events such as System Starts, Stops, Shutdowns, Menu Accesses, etc. The log
holds a maximum of 32 events. The first event (#1) is the most recent and the last event
(#32) is the oldest.
When the log is full, the oldest event is removed from the list to make room for the next
newest event. Navigate through the log using the up and down arrow keys. Press OK to
return to the Home Screen. The log can be cleared using the item at the end of Menu 2.
Clearing the log also resets all event counters to zero.
The following is an alphabetical list of all possible Event Log entries including a brief
description of their meaning and the associated counter which will increment when that
event occurs:
ENTRY DESCRIPTION ASSOCIATED COUNTER
AUTO The system switched to Auto Mode because the user pressed the
MODE and OK button.
AUX ESD The “Aux Temp Mode” setting is set to “Temp ESD” and the Aux Temp
signal exceeded the “Aux Setpoint”.
ESDs
ESD The system shut down as a result of the ESD contact being open. ESDs
FLAME FAIL The pilot went out and could not be relit automatically within the
specified number of attempts (3 attempts on initial start; user defined for
other cases).
Flame Fails
HI PRS ESD The system shut down because the High Pressure Contact was opened
or the “4-20mA High Pressure Setpoint” was exceeded.
High Pressure ESDs
HI VOLT The system input voltage exceeded the High Voltage Alarm threshold. ESDs
HT ESD The “High Temp ESD Setpoint” was exceeded by either “Proc Temp” or
“Aux Temp” (if enabled) and caused the system to shutdown.
ESDs
LEVEL ESD The system shut down because the Level Contact was opened or the
“4-20mA Low Level Setpoint” was dropped below.
Level ESDs
LO PRS ESD The system shut down because the Low Pressure Contact was opened
or the “4-20mA Low Pressure Setpoint” was dropped below.
Low Pressure ESDs
LO VOLT The system input voltage dropped below the Low Voltage Alarm
threshold.
ESDs
LOW ALARM The “Proc Temp” signal dropped below the “Low Temp Alarm Setpoint”.
MANUAL The system switched to Manual Mode because the user pressed the
MODE button.
MENU:CTL Menu 5 “Control” was entered. This will show even if no settings are
modified.
MENU:SETPT Menu 1 “Setpoints” was entered. This will show even if no settings are
modified.
MENU:SYS Menu 4 “System” was entered. This will show even if no settings are
modified.
POC STOP The “Proof of Closure Contact” was open when it should not have been
causing the system to shutdown.
RELIGHT The pilot was successfully relit after it went out unexpectedly. Relights
RESET The system was reset due to a loss of power or a manual press of the
Door Card’s reset button.
Resets
RETRY The Pilot failed to light and one or more retry attempts were made.
RUNNING The system successfully lit the pilot.
START The system switched to Auto mode at a point in time when the pilot was
not lit.
STOPPED The system stopped because the user pressed the STOP button while
the Pilot Valve was open.
SYSTEM ERR An internal system error has occurred. System Errors
TCERR:AUX The AUX Thermocouple is out of range. Thermocouple Errors
TCERR:HT The High Temp Thermocouple is out of range or grounded. Thermocouple Errors
TCERR:PROC The Process Thermocouple is out of range. Thermocouple Errors
