8. Information codes ”InFO”
MULTICAL® 602 constantly monitors a number of important functions. In case of
a serious error in measuring system or installation, "INFO" is displayed and an
info-code can be read by activating the top front key until the measuring unit says
"INFO". The info code is only displayed when the error is present.
Info code Description Response time
0 No irregularities -
1 Supply voltage has been interrupted -
8 Temperature sensor T1 outside measuring range 1…10 min.
4 Temperature sensor T2 outside measuring range 1…10 min.
32 Temperature sensor T3 outside measuring range 1…10 min.
64 Leak in cold water system 24 hours
256 Leak in heating system 24 hours
512 Burst in heating system 120 s.
ULTRAFLOW® info (must be activated CCC=4XX)
16 Flow sensor V1, communication error After reset and 24 hours (at 00:00)
1024 Flow sensor V2, communication error After reset and 24 hours (at 00:00)
2048 Flow sensor V1, wrong pulse figure After reset and 24 hours (at 00:00)
128 Flow sensor V2, wrong pulse figure After reset and 24 hours (at 00:00)
4096 Flow sensor V1, signal too weak (air) After reset and 24 hours (at 00:00)
8192 Flow sensor V2, signal too weak (air) After reset and 24 hours (at 00:00)
16384 Flow sensor V1, wrong flow direction After reset and 24 hours (at 00:00)
32768 Flow sensor V2, wrong flow direction After reset and 24 hours (at 00:00)
If a number of info codes appear at a time, the sum of info codes is displayed. If e.g.
both temperature sensors are outside measuring range, info code 12 is displayed.
9. Plug-in modules
MULTICAL® 602 can be extended by a wide range of extra functions by means of
plug-in modules. The individual modules are briefly described below.
9.1 Base modules
9.1.1 Data + pulse inputs, type 67-00-10
The data terminals are used for connection of e.g. a
PC. The signal is passive and galvanically separated by
means of optocouplers. Conversion into RS232 level
requires connection of data cable 66-99-106 (D-Sub 9F)
or 66-99-098 (USB) using the following connections:
62 Brown (DAT)
63 White (REQ)
64 Green (GND)
