The error signal generated from the tripping of the motor overload cut-out is not cancelled until after the reset of
the motor overload cut-out
and
after the manual enable of the compressor. With the entry of
Motor protect.
N
,
the compressor is switched off with the tripping of the motor overload cut-out. After the reset of the motor
overload cut-out, the compressor is automatically loaded again depending on demand. The control processes
when the motor overload cut-out is tripped for the manual enable (
Motor protect. Y
) and automatic enable
(
Motor protect.
N
) are listed below.
5.12.2 Cylinder head temperature monitoring
The compressor cylinder head temperature is monitored with respect to an upper maximum value. The
maximum cylinder head temperature that results in disabling a compressor and the enabling value must be
specified using the parameters
Comp. OFF temp
and
Comp. ON temp
(menu 3-4). If the upper maximum value
is exceeded, the associated compressor is switched off and disabled for the following control processes after
expiry of a configurable time delay (menu 3-4
"Comp temp del."
).
The compressor remains disabled until the temperature has dropped to the enable level. If the procedure is
repeated multiple times within one day (5 switchings) and there is still more than one compressor available in
the refrigeration compressor pack, the compressor is permanently disabled and must be enabled again
manually (menu 3-1-c Enable comp.stages). The message
Auto disable Cx
is sent here.
Compressor fault in the case of combined control
A compressor fault occurs under the following conditions:
The monitoring of the motor overload cut-out can be activated / deactivated with the parameter
"Mot.cutout C"
(if motor overload cut-out available) using menu 3-1. If the motor overload cut-out is
deactivated, the parameter "
Motor protect. Y/N
" is not displayed and not evaluated.
