7OPERATION
In this chapter we describe, how the device works during operation and how you handle
the device during operation.
7.1 Enable signals
These signals must have a signal level of 24 V (DC) and must be connected to the termi-
nals X3-4 and X3-5 (ZFigure 18– on page 32).
Pulse enable During operation the signal ’pulse enable’ must constantly be created, so that the device
supplies power. Additionally the pulse enable has to be done by the controller
. Both sig-
nals are AND-linked, so the failure of one of these signals results in impulse inhibit of the
power unit.
Quickstop Allow the signal ’quickstop’ only then, if you must stop the installation/device as quick as
possible.
During operation the signal ’quickstop’ must constantly be applied, that the device sup-
plies power.
7.2 Switch-on frequency
The device may not be switched on and off as often as you like. Between two switch-on-
sequences there should be a certain time period, in order to protect the devices/fuses.
NOTE
h refer to the specified waiting time, if you switch on the supply voltage for the device again,
after you have switched off the device.
Imperative for the devices BM441X and BM442X is:
between two switch-on-sequences at least one minute must have passed, before you switch
on the device again. In case you switch off the device beforehand, the durability of the device
will be shortened.
Imperative for the devices BM443X, BM444X, BM445X, BM446X and BM447Xis:
No waiting time has to be complied with.
