Tyco 1540 - Manual (Page 20)

2.18 kWh and kVArh Display Range
The kWh and kVArh display range is limited to 9999999. If the unit is allowed to increment
beyond this value the count will either wrap back to zero (if the 1560/1580 transducer is set to 7
digit mode) or continue to be updated in the 1560/1580 transducer but the display will change to
seven bars. The value will continue to be available via the Modbus output.
2.19 Error Messages
The display repeatedly requests new values from the measurement processor. If there is a
problem obtaining these values, the display will continue to retry but will alert the user by
displaying the message Err1. This message may be seen briefly during conditions of extreme
electromagnetic interference with the normal display returning once the interference has ceased.
If the Err1 message persists, try interrupting, for ten seconds, the auxiliary supply (or supplies)
to the Integra (display and transducer). This may restore normal operation. Also check that
auxiliary power is reaching the transducer and is within specification. Check that there are no
problems with the communications cable between the display and transducer, where applicable.
