Bently Nevada ADAPT ESD Relay Module

ADAPT ESD Relay Module

There are three relay modules in each ESD system. Each Relay Module (part number

323073-01) has five relay contacts. Two of the relays are independent relays, driven by a

corresponding CPU module. The remaining two relays are configurable as either independent

or 2oo3 voted. When using a 2oo3 mechanical trip assembly, a typical installation would

involve a series connection of one independent relay from each of the three relay modules.

Each of the three CPUs would independently drive relays on each of the three relay cards.

When two of the three CPUs drive for trip, the trip assembly would have the inputs it needs to

actuate the safety mechanism. Alternately, 2oo3 relays can be implemented directly on

the ESD system. The remaining fifth relay is a protection fault relay used to convey the overall

health/status of the system. The ADAPT ESD system drives the protection fault relay to

broadcast a condition has compromised the integrity of the system.

Networking Overview

The 3701/55 ADAPT ESD system supports fixed (static) IP addressing as well as DHCP. You can

easily use the Bently Nevada Monitor Configuration software to set the system to any

static IP address or set for DHCP. The system has 6 physical network interfaces in order to

provide 2 interfaces per CPU module. The system should be configured so that each CPU

module is connected to a single subnet through one of the available interfaces.

For redundant communications, the second set of three interfaces can be utilized,

and should be configured for a separate subnet.

Computer Requirements

Bently Nevada Monitor Configuration software will run on most Windows desktop or notebook

computer systems. Bently Nevada Monitor Configuration software is designed to run and

fully tested on Microsoft Windows 7. Software operation is also verified for operation in 32-bit

or 64-bit environments.

Networking Requirements

Bently Nevada Monitor Configuration software requires Ethernet ports with TCP/IP protocol

support to communicate with the 3701/55 ADAPT ESD. The dual ports on each CPU module

should be configured for separate subnets to successfully implement redundant data pathways

when this feature is available. Bandwidth sharing on any network, depending on traffic,

is always a consideration and will affect network performance. Ensure that you have installed

all networking hardware and configured the hardware according to your network administrator’s

specifications.
