DAMAGE TO THE INTERFACES

When devices in operation are connected with interfaces of the temperature control unit,
interfaces may get damaged.

Before connecting, ensure the temperature control unit and the device to be connected are
turned off.
6.2.1 Female RS232 Serial (with adapter cable)
A PC, a SPS or a Process Control System (PCS) can be connected to this jack for remote control of the
controller electronics. Before plugging in the cable, check the settings in the “Interfaces” category
and adjust if necessary.
The interfaces used must meet the specifications of the generally accepted standards.

6.2.2 Connection jack for Pt100 process controller 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) of the application can be significantly less than the setpoint of 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 process control sensor from the Huber accessories program.
