6.3.1 Service interface
This interface is used by the service engineers of Peter Huber Kältemaschinenbau GmbH exclusively
for service purposes. An adapter cable connects this interface to a RS232 serial jack.
6.3.2 RS232 (option) / activation of cooling bath
This connector is used to connect the hanger thermostat with the cooling bath. This enables control
of the cooling bath via the hanger thermostat.
The interfaces used must meet the specifications of the generally accepted standards.
6.3.3 Connection jack for Pt100 process control sensor
A temperature sensor located in the connected application (Pt100, 4-wire technology, Lemosa con-
nector) is connected to the Pt100 connection jack. The external actual temperature is then recorded
and the operating temperature of the temperature control unit is permanently calculated and ad-
justed.
Depending on the operating temperature, isolation losses and exothermic heat, the operating
temperature (flow temperature) at the application can be significantly less than the setpoint for
the application. In this context, safety-critical thresholds for the temperature control fluid must be
strictly observed.
The control results contained in the data sheet can only be achieved with shielded sensor leads.
We recommend the external Pt100 sensors from the Huber accessories.
