PLEASE NOTE:
TO CHECK UNIT FUNCTION
DURING COMMISSIONING, WE
RECOMMEND TESTING THE
Weldsafe 5000 UNDER TRUE
FAULT CONDITIONS. FOR THE
GROUND FAULT FUNCTION, A
SMALL RESISTOR, (e.g. 30 K
AT
480V WILL GENERATE APPROX.
16 mA) CAN BE USED TO CREATE
THIS CONDITION. FOR THE
GROUND CHECKING FUNCTION,
OPEN THE PILOT WIRE.

16-17 C.T. connection
18-19 Ground fault external reset,
Hand=closed Auto=open
22-23 External test button (optional)
25-26 Ground check external reset,
Hand=closed Auto=open
27 Pilot wire if using standard ground
check monitoring
29 Pilot wire if using EOL monitoring
30 Ground connection
EOL End-of-line resistor, 49.9, +/-0.1
L **R1 Loop Resistance Adjustment
This is an internal adjustment that must
made when cable length is very long and
the loop resistance is high (0.5..0.8).
Please check with manufacturer about your
specific application.
