7.4 Information codes
MULTICAL

401 constantly checks a series of vital functions, whereby serious system errors can be detected.
Should one or several serious errors occur in the energy meter, the display will show an ”E” at the left side. In
case of short-duration errors the ”E” will only be displayed as long as the error exists. If an error situation has
existed for more than and hour, the information code will be permanent and can now only be deleted by opening
the meter (see section 7.5
Reset functions).
When the first permanent information code occurs, it is stored in the EEPROM together with the date and the
energy and volume registers at the time the error occured.
The meter’s actual “info code” appears from the last display indication in the main menu, i.e. when the front key
has been activated 4-10 times depending on the selected display configuration. During normal operation the
meter shows “000 info”.
Figure 18
If one or more of below errors occur, the sum of the information codes is shown. E.g. a simultaneous error in both
temperature sensors is shown as “012 info”.
Info Description
+000 No errors found
+002 The information code indicating flow sensor error is activated when the water flow has
continously been below cut-off for 48 hours, while
t has been 20 K
+004
1)
The return sensor does not comply with its measuring range 0…165°C. The sensor can be
short-circuited or disconnected.
+008
1)
The flow sensor does not comply with its measuring range 0…165°C. The sensor can be short-
circuited or disconnected.
+016
1)
Air is detected in the flow sensor (is only indicated as long as the error exists)
+128
2)
The battery must be replaced. This code occurs 12 years after the hour counter was reset.
Table 6
1)
These information codes occur during transport below freezing point as well as during storage.
During installation the info codes are reset as described in section 7.5
Reset functions.
2)
Info code 128 is only active when the meter is ordered with a battery (type number 66-Wx-2xx-xxx).
Use METERTOOL (see section 14) for reprogramming.
