R688 HPM High-Performance Process Manager Service 31
December 2020 Honeywell
2. Equipment Description
2.1 Overview
Introduction
This section describes the assemblies that comprise the High-Performance Process Manager (HPM)
subsystem which is a node on the Universal Control Network (UCN). The UCN interfaces with the Local
Control Network (LCN) through a Network Interface Module (NIM). The modules (nodes) on the LCN
comprise the TPS system.
Component part numbers
The Honeywell part numbers for the items described in this section are listed in “Spare Parts”. See
subsections “Periodic Maintenance Parts” and “Optimum Replaceable Unit (ORU) Parts”.
2.2 Power System Controls
Power Supply Module Control
Two methods of power controlling power
Control of ac power to the Power Supply Modules is provided by two methods when the High-
Performance Process Manager cabinet contains the normal Standard Power System components.
AC power control
All ac power to the cabinet, which includes any Cabinet Fan assemblies, is controlled by a dedicated
circuit breaker that is supplied by the user for each Power Supply Module in the Power System.
Additional ac Power Supply Module control is provided by a power switch that is mounted at the front of
each module.
DC power control
Since the Standard Power System can contain redundant Power Supply Modules, placing a module’s
power switch in the off position does not necessarily remove power from the card files and FTAs in the
cabinet because the second module will continue to supply power unless its Power switch is in the off
position.
If the Standard Power System contains a Battery Backup Pack, 24 Vdc power will continue to be
supplied to the card files and FTAs unless the
BATTERY
switch is placed in the off position, or the
Battery Backup Pack is discharged. All three switches must be in the off position to completely remove
power from the card files.
AC Only Power System
In a cabinet that contains an AC Only Power System, no Battery Backup Pack exists to provide 24 Vdc
power to the card files and FTAs, so control of dc power to the card files and FTAs is provided
exclusively by user supplied ac circuit breakers. When redundant Power Supply Modules exist, each
module has its own circuit breaker that is provided by the user. There is no on-off switch at the front of
the Power Supply Module.
HPMM/IOP Card Power Interrupt Switches
24 Vdc power interruption
The HPMM High-Performance Comm/Control and High-Performance I/O Link cards, and each IOP card
have a 24 Vdc power interrupt switch that is activated by unlocking and lifting the upper card
extractor/insertion lever. Activating either HPMM card’s interrupt switch removes power from both
HPMM cards and the HPM UCN Interface module in the card file, while activating an IOP card power
