ON SCREEN DESCRIPTION POSSIBLE SOLUTIONS
Lvl_Inp The Low Level Contact is Open or the
4-20mA Expansion Card’s Level Input
is reading a value below the 4-20 Level
Low Setpoint. In either case, “Level
Event Restart” is set to “Off”.
Verify proper settings and check wiring.
MbusErr The Modbus Card is not responding. This may indicate that it is not installed correctly or
that it is enabled when not present at all.
ProcTC The Process Thermocouple is open or
otherwise wired incorrectly.
Check wiring.
RemShut Modbus Shutdown Command Received Check the data being sent through the Modbus
connection.
Sys_Err System Error – The Terminal Card is not
communicating with the Door Card.
This may indicate a faulty ribbon cable or incompatible
firmware.
TC_MM The High Temp and Process
Thermocouples are reading
temperatures that are too far apart.
This may indicate a failed thermocouple,
improper wiring, or a damaged Door or
Terminal Card.
Check thermocouple readings with dry block or
process calibrator.
Val_MM The Door and Terminal Card’s setpoints
do not match.
Reset to factory defaults.
6.4 | Warning Messages
The following is a list of warning messages that may flash periodically on the PF2100 display. These
messages indicate a problem that may be developing or a condition from which the system may
automatically restart once cleared. Use the table below to determine the meaning of these messages.
ON SCREEN DESCRIPTION
Check all settings / Other
settings have changed
A major process control setting was changed and the process control setpoints were reset to
factory defaults. This includes the High Temp ESD Setpoint, the Pilot Off Setpoint, the Low Fire
Setpoint, the Process Setpoint, the Low Temp Alarm Setpoint, the Deadband setting, and the Aux
Setpoint.
HI Volt Warning The system voltage is getting close to the High Voltage Alarm threshold and may stop or
shutdown soon.
High Prs Warning The High Pressure Contact is open or the 4-20 Pressure Input is above the 4-20 Pressure High
Setpoint. The contact must be closed for the system to run and the 4-20 Pressure input must be
below the setpoint within 2 seconds after the main valve opens to avoid shutdown.
LO Volt Warning The system voltage is getting close to the Low Voltage Alarm threshold and may stop or
shutdown soon.
Low Temp Alarm The process temperature is below the Low Temp Alarm Setpoint and the Status Contact is Open.
Unit restarted from LVL event The system has recently restarted from a Level event. Press OK to clear this message.
Unit restarted from PRS
event
The system has recently restarted from a Low Pressure event. Press OK to clear this message.
Unit restarted from VLT event The system has recently restarted from a Low or High Voltage event. Press OK to clear this
message.
Waiting: 420 LVL The system will automatically restart once the 4-20 Input Card’s Level Input rises above the Low
Setpoint.
Waiting: 420 PRS The system will automatically restart once the 4-20 Input Card’s Pressure Input drops below the
High Setpoint.
Waiting: HiVolt The system will automatically restart once the system voltage falls below the High Voltage Alarm
Threshold.
Waiting: LoVolt The system will automatically restart once the system voltage rises above the Low Voltage Alarm
Threshold.
Waiting: Low PRS The system will automatically restart once the Low Pressure Contact is closed.
Waiting: LVL The system will automatically restart once the Level Contact is closed.
Waiting:STRT Inp The system will automatically restart once the Start Contact is closed.
