Configuration
Using the parameter
"Freigaberel.
" (menu 6-3), the two semiconductor relays which are otherwise used for
cooling via PWM (Pulse Width Modulation) can be switched to “Enable” operation
.
If the
"Freigaberel
." parameter is set to "ON", the two semiconductor relays are continuously switched on
(enable granted) and the associated status LED lights if the controller signals a refrigeration requirement.
The two semiconductor relays are switched off again (enable withdrawn) if there is no refrigeration
requirement. In addition, the coding switch 6 of the DIP switch S3
must
be set to OFF; for details, see
Function of the analogue outputs 0..10 V
.
If the parameter
"Freigaberel.
" is set to "OFF", the two semiconductor relays cycle (factory setting); for
Control of the expansion valves
).
ATTENTION
Danger due to liquid refrigerant on the suction side of the compressor!
The superheat control is
only performed via the analogue outputs! If the wiring is incorrect, there is a risk of liquid refrigerant
escaping from the evaporator!
When implementing a standalone application with compressor control on the case side, a protective
circuit such as a HP monitor and application-specific, external safety technology
must
be
installed
! The compressors are “only enabled” by the case controller.
Tip:
In addition to the protective circuit, external error signals can be registered via the digital input
(“
External alarm
”, factory setting) and by renaming the message text (e.g. to “HP monitor” or similar)
used to trigger an alarm.
