Log
An overview of events related to fire mode can be viewed in the fire mode log, parameter group 18-1*, or via
the alarm log button on the keypad.
The log will include up to 10 of the latest events. Warranty-affecting alarms will have a higher priority as the
two other types of events.
The log cannot be reset!
Following events are logged:
*Warranty affecting alarms (see par.24-09
Fire Mode Alarm Handling, Fire Mode Alarm Handling)
*Fire Mode activated
*Fire Mode deactivated
All other alarms occurring while fire mode activated will be logged as usual.
NOTE
During fire mode operation all stop commands to the adjustable frequency drive will be ignored, including Coast/Coast
inverse and External Interlock. However, if your adjustable frequency drive incorpora
tes “Safe-Stop”, this function is
still active. See Section “How to Order / Ordering Form Type Code”
NOTE
If in fire mode, it is desired to use the live zero function, then it will also be active for analog inputs other than that used
for fire mode setpoint/feedback. Should the feedback to any of those other
analog inputs be lost, for example a cable
is burned, live zero function will operate. If this is und
esirable, the live zero function must be disabled for those other
inputs.
Desired live zero function, i
f a signal is missing when fire mode is active, must be set in par.6-02
Fire Mode Live Zero
Timeout Function.
Warning for live zero will have a higher priority than the warning “Fire Mode”.
NOTE
When setting the command Start Reversing [11] on a digital input terminal in par.5-10 Terminal 18 Digital Input, the
adjustable frequency converter will understand this as a reversing comm
and.
