Proline Kryomats
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 remote control:
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 (

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
remote control, external solenoid valve, etc.).
An RS 232/485 interface (65S) at the back of the Command remote control.
4.8
Interface modules (accessories)
The Master control element can be supplemented with further interface modules, which are simply inserted into two
module slots (
3) at the back of the control head.
The following modules are currently available:
1.
RS 232/485 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
RS 232 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.
