3001H Hardware failure
*1 When the error occurs, the count operation does not start for all channels.
*2 Since the error does not occur separately on each channel, the error code is stored in 'CH1 Error code' (Un\G9).
*3 The count operation stops for the channel where the error has occurred.
*4 The counting operates normally for channels where no error has occurred.
*5 The count operation continues without reset for the channel where the error has occurred.
*6 When the error occurs, 'Module READY' (X0) turns off.
Description and cause
A value other than 2 to 60 is set in CH Number of
moving average processing.
A value other than Pre-scale function invalid (0) to
0.0001 (5) is set in CH Pre-scale function
selection.
A value other than 0 to 32767 is set in CH Pre-
scale setting value.
A value other than Warning output function invalid
(0) and Warning output function valid (1) is set in
CH Warning output selection.
A value other than 0 to 32767 is set in CH Warning
output setting value upper/upper limit.
A value other than 0 to 32767 is set in CH Warning
output setting value upper/lower limit.
A value other than 0 to 32767 is set in CH Warning
output setting value lower/upper limit.
A value other than 0 to 32767 is set in CH Warning
output setting value lower/lower limit.
Some values set as warning output setting values do
not satisfy the following condition.
Upper/upper limit  Upper/lower limit > Lower/upper
limit  Lower/lower limit
A value other than Count cycle change function
invalid (0) and Count cycle change function valid (1)
is set in CH Count cycle change function selection.
A value other than 1s (0) to 500ms (3) is set in CH
Count cycle setting value.
A hardware failure has occurred in the module.
Action
Set CH Number of moving average processing to
2 to 60.
Set CH Pre-scale function selection to a value
from Pre-scale function invalid (0) to 0.0001 (5).
Set CH Pre-scale setting value to 0 to 32767.
Set CH Warning output selection to Warning
output function invalid (0) or Warning output function
valid (1).
Set CH Warning output setting value upper/upper
limit to 0 to 32767.
Set CH Warning output setting value upper/lower
limit to 0 to 32767.
Set CH Warning output setting value lower/upper
limit to 0 to 32767.
Set CH Warning output setting value lower/lower
limit to 0 to 32767.
Set the following buffer memory areas so that the
condition of Upper/upper limit  Upper/lower limit >
Lower/upper limit  Lower/lower limit is satisfied.
• CH Warning output setting value upper/upper
limit
• CH Warning output setting value upper/lower
limit
• CH Warning output setting value lower/upper
limit
• CH Warning output setting value lower/lower
limit
Set CH Count cycle change function selection to
Count cycle change function invalid (0) or Count
cycle change function valid (1).
Set CH Count cycle setting value to a value from
1s (0) to 500ms (3).
Power off and on the module.
If the error occurs again, the possible cause is a
failure of the module. Please consult your local
Mitsubishi representative.
