FlexTest Controller Configurations
58
Control voltages for hydraulic power units vary between models. The
interface between the Model 494.41 System board and an HPU consists of
24-volt logic signals.
Connecting J25 to a non-compliant HPU can damage the board.
Do not connect 24 V DC relay circuitry or 115 V AC circuitry to connector J25 on
the Model 494.41 System board.
Cable specification To maintain EMC compliance, J25 HPU cables must comply with the following
specifications:
Connector—15-contact, type-D, female EMI connector.
Backshell–EMI metallized plastic or metal.
Cable—22 AWG, 10-conductor with braided shield with the shield connected to
metallized plastic or metal backshell to the chassis.
Jumper plug required If connector J25 HPU is not used, you must install a jumper plug to maintain the
integrity of the interlocks. Use jumper plug part number 039-713-301 or jumper
pins 1–7, 2–3–5, 6–9, 8–10–11–12.
