10.3 Error display
The table below shows the error messages displayed on the screen and the countermeasures.
Type Message Trouble shooting
Hardware
OUTPUT OFF
Turn on the OUTPUT ON/OFF switch on the panel or
OUT remote switch.
AUX.OUT.IS SHORT
Open the auxiliary power output terminal(S1
~
S2) and check
the output voltage. If the output voltage is DC 12V, check the
load (less 2A or not) and outer wiring. If the output voltage is
not obtained, the LE-40MTA-E is defective.
System
parameter
REEL ERROR
Check *2 and *3 of selection
item described in page 50.
When completion of the ini-
tial setting is confirmed or
when the AUTO switch is
pressed while the operation
/stop input is turned off,
error check is performed.
SET PARAMETER
The minimum diameter and
maximum diameter must be set
in accordance with the reel
diameter input of 0
~
5V.
Tension
detector
Zero/Span
adjustment
THE DETECTION
ROLLER IS TOO HEAVY!
It is thought that the mass of the tension detection roller is
heavier than the rated load of the tension detector. Check
the mass of the detection roller. It is necessary to select the
detector again if necessary. Refer to page 45 for details.
SPAN TUNING TARGET
WEIGHT IS TOO LIGHT!
The weight at the span adjustment is too light in 1/3 or less of
the tension full scales. Make the weight heavy and execute
the span adjustment again.
DETECTED LOAD IS
TOO LIGHT!
The output voltage of the tension detector is too low.
Because the rated load of the tension detector is larger than
that of the drive tension, it is necessary to select the tension
detector again. Refer to page 45.
CHANGE WH _ - GR _
CONNECT WIRE!
The wiring for the tension detector is opposite. Exchange the
terminals [GRR] and [WHR]each other as well as the termi-
nals [GRL]and [WHL]each other. Refer to the part of the ten-
sion detector on page 14 for details.
NO LOAD TO THE
DETECTION ROLLER! Put the weight on the tension detection roller and execute
the adjustment again.
DETECTED LOAD
IS TOO HEAVY!
The output voltage of the tension detector is too high.
Because the rated load of the tension detector is smaller
than that of the drive tension, it is necessary to select the
tension detector again. Refer to page 45.

TURN OFF SW
Turn off the write protect switch in the memory cassette.

After writing or reading, data is automatically collated.
If this error message is displayed,replace the memory cas-
sette.
