4.8 Interface modules (accessories)
Other interface modules can be inserted into two slots (refer to Section 8).
The following modules are currently available:
1. RS232/485 Interface Module (Order No. LRZ 913) with 9-pole SUB-D socket. Electrically isolat-
ed through optocouplers. Command set largely compatible with the ECO, Ecoline, Proline, Inte-
gral 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 0 and 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 out-
puts (changeover, max. 30 V / 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 8.5.1.
4. Contact Module (Order No. LRZ 914) with connector to NAMUR NE28. Functionality as
LRZ 915, but only one output and one input on each of two DIN sockets. Coupling socket 3-pole,
LAUDA Order No. EQD 047 and coupling plug 3-pole, LAUDA Order No. EQS 048.
Further details can be found in section 8.5.2.
5. Profibus (LAUDA Order No. LRZ 917).
Further details can be found in the operating instructions YAAE0020 of the Profibus Modules.
4.9 Refrigerating unit
The refrigerating machine mainly consists of one or two fully hermetically sealed compressors. The dis-
sipation of the condensation and motor heat takes place via a fan-ventilated laminated condenser.
Here, fresh air is drawn in at the front of the unit, heated towards the back and output at the side. To
ensure proper air circulation the ventilation slots must not be restricted. (
þ
6.1).
The condenser must be cleaned regularly to prevent soiling (
þ
9.3.2.1). The SelfCheck Assistant out-
puts a warning signal when the condenser is soiled.
On water cooled devices the heat dissipation takes place via a plate-type heat exchanger or a bundle
tubing heat exchanger using cooling water. Regular cleaning is also required here depending on the
water contamination
(
þ
9.3.2.2).
The compressors are equipped with over temperature cutouts which respond to the compressor tem-
perature and the compressor current consumption. In addition the refrigerating system is backed up by
a pressure control device against over pressure. The refrigerating unit is normally switched in automati-
cally, but can be switched manually via the operating menu (
þ
2.2).
When the fault circuit trips, the refrigerating unit is also switched off.
