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-40MTB-E is defective.

REEL ERROR 
Check *2 and *3 of selection 
item described in page 81. 
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.

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  76 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 76. 
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 76.

The teaching result of the velocity gear is out of the elec-
tronic gear set range. Check the specifications of the mea-
sure pulse rate, reel pulse number per rotation, gear ratio.
