Emergency operation
The gate motor drive can switch over automatically from automatic mode to
emergency operation. This automatic switch-over can only take place after a
"Function emergency situation" input signal which is generated by a fire
emergency room. Only the one movement (OPEN or CLOSED, depending on
programming) that is requested will be performed at dead man's mode speed in
this operating mode. The safety facilities are also activated during this movement.
The movement can be interrupted by pressing and holding the STOP key or by a
safety device being triggered. When this interruption no longer applies, the gate
will immediately continue to move. At the end of the emergency movement and
after the signal ("Function emergency situation") has been reset, the software of
the motor drive will initiate a restart to enable safe switch-over to automatic
mode.
Any static active OPEN or PARTLY OPEN signals are ignored by the motor drive in
this operating mode.
Just as the command triggered by an OPEN or CLOSE command key being pressed
cannot be performed when a program is started, a static active "Emergency
situation" input signal will also not be carried out when switching on the motor
drive.

AUTOMATICALLY CHANGING OPERATING MODES
The gate motor drive can switch over from automatic mode to emergency
operation if it has been programmed to allow this and the HMD230/IGD
recognizes a corresponding "emergency situation" signal from a fire emergency
room. This operating mode will then be performed until the motor drive is
restarted.
If electronic safety facilities on the gate are out of operation (e.g. faulty
photocell), the motor drive can automatically switch over from automatic mode to
hold-to-run-control. This automatic switch-over will take place only for the
individual motor movement that has been started and only if the key provided for
hold-to-run-control is pressed. After this, the motor drive will switch over to
automatic mode again, but if a new fault occurs or if the fault is not remedied, the
system can switch over to hold-to-run-control again for the next movement.
Changing between operating modes is possible in the following directions:
•
Automatic mode
->
Hold-to-run-control mode
