An external input range alarm occurs when a 4 to 20-mA or 1 to 5-V input sig-
nal or variable resistor main setting input is outside of the input range. Check
whether the input signal range is correct and whether the external resistor wir-
ing is disconnected. Then perform a reset operation (using the ENT/RST Key,
a reset input, or a reset command via communications).
An external duty input alarm occurs when an external variable duty setting
input is outside of the input range. Check whether the external resistor wiring
is disconnected. Then perform a reset operation (using the ENT/RST Key, a
reset input, or a reset command via communications).
A total run time alarm occurs when the total run time exceeds the time set in
the Total Run Time Threshold parameter [P17]. Either increase the setting for
the Total Run Time Threshold parameter [P17] in the initial setting level, or
reset the total run time by setting the Reset Total Run Time parameter [P27] to
1. Then perform a reset operation (using the ENT/RST Key, a reset input, or a
reset command via communications).
A communications timeout alarm occurs when communications with the host
controller fail because the time set in the Communications Timeout Time
parameter [P26] is exceeded. Check whether the host device is operating nor-
mally, and whether there is a burnout in the communications lines. The error
status will be cleared by correctly writing the main setting from the host.
To not have communications timeouts detected, set the Communications Tim-
eout Time parameter [P26] to 0.
