Volume Conversion Device EK260
46 Elster GmbH
I1 Alarm Alarm on Input I1 Message 2 in St.1
With a connected encoder ( Md.I1 = 5,
→
3.10) no actual volume could be measured
for more than 20 seconds (
→
4.5). Possible causes are, for example, a cable
breakage or low batteries in the EK260.
In this case the substitute values p.F (
→
3.3) and T.F (
→
3.4) are used for volume
conversion and disturbance quantities are counted for Vb and Vm (
→
3.1, 3.2 ).
T Inp. Error No usable input value for temperature Message 2 in St.5
The signal, Bin.T (
→
3.9), measured on the temperature input is outside the valid
range. The sensor may not be correctly connected.
In this case the substitute temperature
T.F (
→
3.4) is used for volume conversion and
disturbance quantities are counted for Vb and Vm (
→
3.1, 3.2).
p Inp. error No usable input values for pressure Message 2 in St.6
The signal, Bin.p (
→
3.9), measured on the pressure input is outside the valid range.
The sensor may not be correctly connected.
In this case the substitute pressure
p.F (
→
3.3) is used for volume conversion and
disturbance quantities are counted for Vb and Vm (
→
3.1, 3.2).
Data restore Data has been restored Message 3 in StSy
The device was temporarily without any power supply. Possibly during battery
replacement, the battery was removed before the new one was connected. Data has
been retrieved from the non-volatile memory (EEPROM).
The retrieved counter readings and the clock values are possibly out of date:
If a manual data backup was carried out with the command "Save" before the voltage
failure(
→
3.9), the counter readings and time correspond to the state at the time of
the data backup.
Without manual data backup, the counter readings and time are retrieved with the
state at the end of the last day before the voltage failure.
Outp.1 Error Error on Output 1 Message 4 in St.1
Outp.2 Error Error on Output 2 Message 4 in St.2
Outp.3 Error Error on Output 3 Message 4 in St.3
Outp.4 Error Error on Output 4 Message 4 in St.4
The volume pulses to be passed through an output are temporarily saved in a puls e
buffer. The buffer can accommodate 65535 pulses. If the volume to be output is
continuously greater than that which can be output in the form of pulses, the pulse
buffer continually fills and will eventually reach its maximum state. If then further
pulses arrive, these can no longer be temporarily saved and are lost. The pulse
buffer remains at its maximum state in this case. Meldung „4“ weist darauf hin, dass
auf diese Weise Impulse verloren gingen.
If the pulse buffer drops below the level of 65000 pulses, the message is cleared
again.
To rectify the cause of this problem, the cp value of the output (
→
3.11 Output list)
can be reduced or the output frequency (address 1 :617) increased with an AS-200
Readout Device or the WinPADS Parameterisation Software.
With a change of the output cp value, the corresponding input buffer is cleared .
