Other benefits
There is a programmable switch-on and switch-off threshold for each compressor.
For example, if only two compressors need to be controlled, the other two circuit hystereses are
available for further monitoring.
In addition to the base load changeover control function, the following special functions are also
available:
-Freely programmable integrated timer.
-Free assignment of base load and load change function.
That means that the base load compressor is always running, and only
the load change compressors are changed.
-Free programming of a ball valve function, for up to three compressors.
-Four separate inputs for power-on duration or operating hours or
number of faults or number of switching cycles.
-The next compressor is switched on after the elapse of an adjustable waiting
time, – if desired, even without reaching its switch-on threshold.
-The function ‘remote release input’ switches off the GLW 4 when it reaches the
next switch-off threshold, e.g.
during a maintenance shutdown.
-Program protection: Programming is only possible if you know the password!
-All settings are separately switchable!
-Free programming of a potential-free changeover contact as an alarm output.
The GLW 4 from CONDOR PRESSURE CONTROL GMBH provides an electronic solution of a base
load changeover controller for a maximum of four compressors. The GLW 4 has to be clipped on to a
35mm-wide top-hat rail conforming to the standard DIN EN 50022. The system is equally suitable for
controlling piston compressors as well as screw compressors.
Changing the set switching points enables the equal loading of all compressors. The switching points
are automatically changed by inputting ‘LOAD CHANGE TIME’. The load change time is adjustable be-
tween 0 to 999.9 h. If the input ‘Off’ is entered, load changing is omitted. When ‘BASE LOAD’ is entered,
the connected compressor is not taken into account during load change.
