Unit description
19
When the level is too low, with overtemperature, or with other alarms the SelfCheck Assistant switches
the heater off on all poles. The pump and the refrigerating machine are also switched off.
This switch-off under fault conditions is retained, i.e. after the fault is rectified, the fault must be reset
(released) on the Master operating panel with the
key.
Other unit functions are described in the appropriate sections and in Section 7. (Starting up).

Programmer and ramp function
Master control element:
No programmer provided.
Command control element:
The units are equipped with a programmer function, which enables five temperature/ time programs to
be saved. Each program consists of a number of temperature/ time segments. These also include
details of how often the program is to be executed. Up to 150 segments can be distributed amongst the
five programs.
With the ramp function, a rate of change can be directly entered in K/ unit time (

4.7
Interfaces
The device is equipped in series with the following sockets:
•
One socket (10S) for the connection of an external Pt100 temperature probe.
•
Two sockets (70S) for the connection of components via the LAUDA equipment bus (cooling
section, Command control element, external solenoid valve, etc.).
•
An RS232/485 interface (65S) at the back of the Command control element.
4.8
Interface modules (accessories)
The Master control element can be supplemented with further interface modules, which are simply
inserted into two module slots (

The following modules are currently available:
1.
RS232 / 485 Interface Module
(Order No. LRZ 913) with 9-pole SUB-D socket. Electrically
isolated through optocouplers. Command set largely compatible with the Ecoline, Integral XT and
Integral T Series. The RS2323 interface can be directly connected to the PC with a cable wired
1:1 straight through (Order No. EKS 037).
Further details can be found in section 8.3.
2.
Analog Module
(Order No. LRZ 912) with two inputs and two outputs on 6-pole DIN socket. The
inputs and outputs can be set independently as 4...20 mA, 0...20 mA or 0...10 V interface.
Further details can be found in section 8.4.
3.
Contact Module
(Order No. LRZ 915) on 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 (Order No. EQM 030) and plug case (Order No. EQG 017).
Further details can be found in section 8.5.
4.
Contact Module
(Order No. LRZ 914) with connector to NAMUR NE28. Functionality as
LRZ 915, but only one output and only one input on each of two DIN sockets. Coupling socket
3-pole (Order No. EQD 047) and coupling plug 3-pole (Order No. EQS 048).
