8.3 Serial interfaces RS232/485
RS232/485 interface Module (order no. LRZ 913) with 9-pole SUB-D socket. Electrically isolated by
optocoupler. With the LAUDA instruction set essentially compatible to the ECO, Ecoline, Proline, Inte-
gral XT and Integral T Series. The RS232 interface can be connected directly to the PC with a 1:1
through-contact cable (order no. EKS 037).
Interface description and commands see chapter 7.17.
8.4 Analogue module
The analogue module (order no. LRZ 912) has 2 inputs and 2 outputs which are brought out on a 6-pole
DIN socket to Namur Recommendation (NE28). The inputs and outputs can be set independently as 4 –
20 mA, 0 – 20 mA or 0 – 10 V interface. Various functions can be selected for the inputs and outputs.
Accordingly, the signal on the input is interpreted differently and different information is output via the
output connection.
In addition the interfaces can be scaled freely according to the set function.
For measuring transducer is 20 V DC available.
The following values can be specified via the input:
- Setpoint temperature with function: MN tS or Set temperature .
- Return flow temperature T
ret
- External actual temperature with function: MN tE or ext. actual temperature .
- Pump power with function: MN PP or Pump power .
The following values can be specified via the outputs:
- Setpoint temperature with function: Master: MN tS or Command: Set temperature .
- The temperature source with which active control occurs: MN tC Controlled temp. .
- Outflow temperature: MN t1 or Outflow temp. .
- External actual temperature from Pt100: MNtEP or Temp. external Pt100 .
- External actual temperature from analogue input: MNtEA or Temp. external analogue .
- External actual temperature from the serial interface: MNtES or Temp.external serial .
- Actuating signal: MN Y or Actuating signal .
- Pump power: MN PP or Pump power .
- Pump speed: MNtEn or Pump speed .
- Pump pressure .
In addition the interfaces can be scaled freely with
L =0
/ H 10=0 in % or minimal value / max-
imal value according to the set function.
For example: 4 mA corresponds to 0 °C and 20 mA corresponds to 100 °C.
