CAUTION
Avoid the described hazard: otherwise minor or medium physical injury or
damage to property will result.
WARNING
Avoid the described hazard: otherwise there is danger from electric voltage
that could lead to death or serious physical injury.
For your safety
For safe operation and to avoid personal injury and equipment damage through operating error,
always read these instructions, become familiar with the device, and follow all safety instructions on
the product and in this document, as well as the safety guidelines of Wurm GmbH & Co. KG
Elektronische Systeme. Keep these instructions ready to hand for quick reference and pass them on
with the device if the product is sold.
Wurm GmbH & Co. KG Elektronische Systeme accepts no liability in case of improper use or use for
other than the intended purpose.
Target group
These instructions are intended for service technicians.
Intended use
The FVB110-PAT is a field module for switching and monitoring 1
compressor.
WARNING
Danger to life from electric shock and/or fire!
Switch off the power to the entire plant when installing, wiring or removing! Otherwise a
mains voltage and/or external voltage may still be present even if the control voltage is
switched off! Always remove both power plugs (230V~ and N)!
The wiring of the device should be carried out only by a qualified electrician!
Use only the correct tools for all work!
Check all wiring after connection!
Take note of the maximum loads on all connections!
Never expose the device to moisture, for example due to condensation or cleaning
agents!

Take the device out of operation if it is faulty or damaged and is therefore compromising
safe operation!
Do not open the device!
Do not repair the device yourself! If required, send it in for repair with an exact
description of the fault!
CAUTION
Electromagnetic interference can cause faults!
Use only shielded data lines and place them far away from power lines!

NOTES
The CAN bus shield must be connected at only one (!) CAN bus end by means of the
6.3mm connecting lug with PE.
Further information on the CAN bus can be found in the FRIGOLINK bus system
manual.

This device is designed for top-hat rail
installation. The housing is of a standard size
and is also suitable for installation in fuse boxes,
distribution switch boxes or electric boxes of
refrigeration units.
The devices can be positioned immediately next
to one another and without gaps.
Place the device with the upper guide edge on
the top-hat rail.
Then press the device gently downward until it
engages with the fastening safety catch on the
top-hat rail.

Fault inputs that are not used
In order to obtain correct fault information, fault inputs that are not used must be jumpered with the
fault signal that is connected upstream within the alarm routing. The input "Operation" (terminal 22) is
used for measuring the operating hours. If no corresponding signal is available from the machine
protection, then it is advisable to jumper the output relay.
Monitoring function / emergency program
In the event of an F-BUS fault, the field module enters an emergency program corresponding to the
operating mode. If a problem with the cover identification arises at the same time, then all of the output
relays are switched off and the analogue output "AO" is set to 0V.
Module addressing
Make sure that each of the 8 field modules per master module (HVI-G3/G4: 12) has a different module
address. Permissible addresses are the values 0…7 (HVI-G3/G4: 0…B). No other settings are
permitted. The address of the module FIO001B / FIO-PAT and the addresses of the field modules
FVBxxxB / FVBxxx-PAT must not overlap. In the event of an address collision, an entry is made in the
fault list of the master module and the LED " " (fault) on the field modules flashes.
