2. Load the traction motor to 100 amps in 1A and record the
voltage (V
L
) at the control positive and negative power
terminal.
3. Calculate voltage drop (V
Drop
) as follows:
V
Drop
= V
O
- V
L
4. Use the table below to determine the appropriate setting
using the calculated V

( Push CONT 3 )
This function allows for the adjustment of the time delay for
the line contactor drop out.
(VAL x 0.5) + 1.5 = seconds before contactor drop out
Example: Setting of 10 = (10 x 0.5) + 1.5 = 6.5 seconds
FUNCTION 19 MAINTENANCE CODE TENS AND UNITS
HOURS SET
