• Cable for load frames with crosshead locks built after 1985, 18 AWG, 8
conductor with overall foil shield Alpha 5388C or equivalent with drain
wire connected to pin 9 at both ends of the cable.
• Cable for all load frames without crosshead locks–22 AWG, 6 conductor
with overall foil shield Alpha 5386C or equivalent with drain wire
connected to pin 9 at both ends of the cable (pin 9 may be pin E at the load
frame).
Jumper plug If connector J29 is not used, you must install a jumper plug to maintain the
integrity of the interlocks. Use jumper plug 100-007-947 or jumper pins: 3 and 4;
5 and 7; 8 and 13.
Station stop
The Emergency Stop connection can also be configured as a station stop. When
this is done, be sure that you have other Emergency Stop boxes near by. Pressing
Station Stop will shut down the hydraulics to an individual station without
shutting down power to the hydraulic power unit.
Note A Model 493.73 HPU Transition Board must be installed for the
Emergency Stop connection to be enabled.
