Abort Connections
Abort connections of the Safety High-Tech Status Unit are supervised for open-circuit, short-circuit and ground-
fault conditions. Abort connections on the circuit board of the Status Unit are labeled Hold. Hold and Abort
functions are identical. To provide supervised connections on the Abort terminals:
Connect the 6.8 K Ohm EOL resistors across the Hold terminals of the Status Unit when inputs are unused.
The figure below illustrates Hold connections for the Status Unit:

Hold Input Connections
1 Connect a 470 Ohm trigger-resistor, SHE80003 in series with one-leg of the normally open switch.
2 Connect a 6.8 K Ohm EOL resistor, SHE80002 in parallel with the normally-open-switch.
3 Connect wiring from one-side of the 6.8 K Ohm EOL resistor, SHE80002 to one-side of the Hold input.
4 Connect wiring from the opposite-side of the 6.8 K Ohm EOL resistor, SHE80002 to the opposite-side of the
Hold input.
