Error (ALM indicator: Flashing)
One of the following items 1 to 3 has occurred.
1. The sensor circuit is disconnected or the temperature setting is out
of the specified range.
2. The temperature setting is out of the specified range.
3. There is a problem in the internal circuits.
Corrections
1. Check for incorrect wiring, circuit disconnections, short circuits,
and whether the input type and temperature settings are correct.
2. Disable SV Protect Mode.
3. If the wiring and settings are correct, reset the power supply.
If the Unit resumes normal operation, the problem may have been
caused by noise.
If the Unit does not resume normal operation, it must be replaced.
* Latching and the SV Protect Mode are stored in non-volatile
memory. An error may occur if the data is updated more than one
million times.
* If you press and hold the LATCH_RESET button for 5 seconds or
longer, the SV Protect Mode will go into effect.
When SV Protect Mode is enabled, the PWR indicator flashes.
To disable the SV Protect Mode, press and hold the
LATCH_RESET Button for at least 5 seconds.
