J28 HSM Connections for the Model 494.41 System Board
HSM control (off/low/high or proportional) is software configurable. The Model
494.41 Board provides separate 24-volt, low-pressure and high-pressure outputs
that drive the HSM low- and high-pressure solenoids. Proportional control
provides a current output from 0 to 0.78 A.
Note The Model 494.41 Board cannot be used with 115 V AC HSMs.
Applications that use 115 V AC HSMs require an external converter box
(such as a Model 413.08), which is used with this board.
Cable specification
To maintain EMC compliance, J25 HPU cables must comply with the following
specifications:
Connector—4-contact, CPC-4P, male EMI connector.
Proportional Control Cable—18 AWG, 2-conductor with foil shield with the
drain wire connected to pin 3 of the CPC connector.
Off/low/high Control Cable—18 AWG, 3-conductor with foil shield with the
drain wire connected to pin 3 of the CPC connector.
