Device description
28.04.10/ YACE0088
4.4 Materials
All parts coming into contact with the heat transfer liquid are made of high quality material suitable for the
operating temperature. Non-rusting stainless steel, and temperature-resistant and to a large extent sol-
vent-resistant plastics are used.
4.5 Programmer
The devices are equipped with a programming function. This function provides five temperature/time
programs. Up to 150 segments can be spread over the five programs. (
Ì
7.8).
4.6 Interfaces
In the basic version the GOLD devices are equipped with a mini-USB interface. This enables, for exam-
ple, the connection of a PC and operation with the thermostat control software Wintherm Plus. In addi-
tion software updates are possible via the USB interface. The connecting lead is not included in the
items supplied with the thermostat. When connecting up, make sure the correct plug is used.
4.7 Interface modules (accessories)
The devices can be supplemented with further interface modules which are connected to the rear of the
control head in two module slots (
Ì
8) and are inserted.
The following modules are currently available:
1. Analogue Module (LAUDA order no. LRZ 912) with two inputs and two outputs on a six-pole
DIN socket. The inputs and outputs can be set independently of one another as a 4...20 mA
or 0...10 V interface. 20 V is brought out on the socket as a power supply for an external sen-
sor with evaluation electronics.
2. RS 232/485 Interface Module (LAUDA order no. LRZ 913) with nine-pole SUB-D socket.
Electrically isolated using optocouplers. Using the LAUDA instruction set, extensively com-
patible to Proline, Proline Kryomat, Integral XT and Integral T series. The RS232 interface
can be connected directly to the PC with a 1:1 connected cable (LAUDA order no. EKS 037).
3. Contact Module (LAUDA order no. LRZ 914) with connector to NAMUR NE28. Range of
functions as for LRZ 915, but only one output and one input on each of two DIN sockets.
Coupling Socket three-pole, (LAUDA order no. EQD 047) and Coupling Plug three-pole,
(LAUDA order no. EQS 048).
4. Contact Module (LAUDA order no. LRZ 915) for 15-pole SUB-D socket. With three relay
contact outputs (changeover, max. 30V/0.2A) and three binary inputs for control via external
voltage-free contacts. Plug 15-pole, (LAUDA order no. EQM 030) and Plug Housing (LAUDA
order no. EQG 017).
5. Profibus Module (LAUDA order no. LRZ 917).
You will find further information in the Operating Instructions YAAD0020 for the Profibus
Module.
6. Pt100/LiBus Module (LAUDA order no. LRZ 918)
External Pt100 : For the connection of an external temperature sensor.
LiBus : For the connection of the Command remote control unit from the Proline
equipment line and other accessories, such as a solenoid valve for cooling water control, a
reverse-flow protection device or a through-flow cooler (DLK) with LiBus connection.
