J25 Hydraulic Power Unit Connection
Connector J25 HPS on the Model 493.73 HPU transition board controls the
hydraulic power unit (HPU).
• The module produces 24 V logic signals to control the HPU.
• The Model 493.07 HPU Converter Box allows any MTS HPU to be
connected to the chassis with the following exceptions:
– 506.52-.92 HPUs (24 volt, PLC compatible)
– All Series 505 HPUs
The converter box is used with other configurations. For more information
see
“Hydraulic Configurations” on page 243.
Control voltages for hydraulic power units vary between models.
The HPU interface between the Model 493.73 HPU transition board and an
HPU is 24 volt logic signals. Connecting J25 to a non-compliant HPU can
damage the module.
DO NOT connect 24 V DC relay circuitry or 115 V AC circuitry to the HPU
connector J25.
Service LED The Service LED turns on when electrical power is applied and it turns off when
the chassis makes contact with the personal computer and processor has
successfully booted.
Cable specification
J25 HPS is a 15 pin type D male connector.
• 15-contact type D female EMI connector.
• Cable—24 AWG, 10 conductor with overall foil shield, (Carol C0745 or
equivalent) with drain wire connected to metallized plastic backshell to the
chassis.
Jumper plug required
If connector J25 HPS is not used, you must install a jumper plug to maintain the
integrity of the interlocks. Use jumper plug PN 039-713-301 or jumper pins: 1–7,
2–3–5, 6–9, 8–10–11–12.
