1 Introduction
This document describes the HVC controller including installed software. This controller will work in either 12 volt or 24 volt applications.
This durable controller has been designed with a rugged aluminum enclosure, allowing it to operate in harsh environments having achieved IP67 rating. It can be mounted directly on a valve or in demanding vehicle operations outside of the cab. HUSCO environmental standards (EMC, EMI, shock, etc.) are much higher than industry standards achieving EMC Immunity of greater than 150 V/meter and shock in excess of 100 G. Integrated pressure sensors (350 bar) and temperature sensors (-40 to 125C) monitor valve applications. The industry standard Deutsch connector provides access to 4 independent high-side PWM drivers (50 to 200 Hz with 0 to 2200 milliamps). Current feedbacks provide closed loop current control with our industry leading current servo and include integrated fly back diodes. The controller can be configured using the HUSCO Diagnostic Tool on the J1939 CAN bus. The controller is reprogrammable (512K Flash memory), allowing different CAN baud rates or access to the multiplexed frequency inputs.

2.3 CAN
The CAN connection is CAN 2.0B and includes J1939. The CAN baud rate defaults to 250K. The controller will claim Node Address 0x82 by default, if required it can be configured to claim other Node Addresses.
2.4 CAN Inputs CAN messages sent to the controller are expected to be received periodically. Outputs controlled via CAN will be turned off if the message is not received within the minimum rate.
2.4.1 Current Command Message The messages are expected to be received periodically with a period between 10 milliseconds and 500 milliseconds (minimum reception rate).
