More and more companies today need an economic operating air pressure system. Thereby, several compressors are often connected to each other. Since 1995 Condor GLW controls have been used to monitor up to 4 compressors in primary load set up. The GLW 4 evaluates the mains pressure and rotates the connected compressors on a time-dependent basis. If desired, an internal timer is available e.g. shift work applications.
Following functions can be activated:
· Internal pressure transducer 0 to 16 bar · Connection of an external pressure transducer, two-wire 4 to 20mA · Programmable internal time switch (controls up to 6 profiles) · Programmable primary load and load changeover functions, allowing for the primary load compressor to operate without taking part in the rotation process. Only the load changeover compressors are rotated. · Programmable ball valve control with max. 3 compressors · Direct switchover after the load changeover time has elapsed. · Four digital inputs (e.g. for hourmeter ) · Input: bridge time switch · Input: remote release · Parameter password protection · Units reversible bar/psi
