Unipump with echo:
This function is used to monitor if the Unipump being controlled by the POCO is
operating in synchronisation with the Unistat’s own pump. The operating status of the
Unipump can be signalled via a normally open contact by connecting to a “level”
connector. If the Unipump does not operate with the machine, a fault signal will be
generated.
This operating mode is very useful if the Unipump has to be monitored, either to
guarantee the desired temperature control or to avoid unintended heating of the thermal
fluid.
Programmer:
The relay is controlled by a command from a segment within a temperature profile
running on the programmer. Please also note the menu point on
Enter program.
Check int. temp. abs. (check internal temperature absolute)
The relay switches when the current internal temperature is outside the specific band
determined by the maximum and minimum temperature limits. Outside this band POCO
is active, within the band POCO is inactive.
Check proc. temp. abs. (check process temperature absolute)
The relay switches when the current external temperature is outside the specific band
determined by the maximum and minimum temperatures. Outside this band POCO is
active, within the band POCO is inactive.
