7.1.8 Features and installation informations
 The outward and return lines of the essernet
®
connection must always be routed separately from one another
other; i.e. they must not be installed in one multipair cable or in one cable duct. Joint installation may affect
the function or, if the cable/cable duct is destroyed, can cause complete failure of the connection if the outward
and return cables become disconnected.
 Attach the cable shielding for the essernet
®
connecting cables to the corresponding terminal block!
 The respective overvoltage protection should be used for both essernet
®
module types.
 Always avoid installing an essernet
®
loop together with power supply cables, motor control cables, phase
control cables or other performance-related switching cables. Observe corresponding standards and
guidelines.
essernet
®
-modul 62, 5 kBd:

Use communication cable I-Y (St) Y n x 2 x 0,8 mm with appropriate labelling or designated fire protection
cable - max. length 1000 m.
 For this transmission speed a suitable cable must be use, twisted-pair cable with plastic insulation.
Other cables, e.g. paper covered cable, control leads (NYM) or smaller diameter are not suitable. For each
A+B connector a separate pair of wires must be used. If a fourfold twisted-pair wire is used the second pair
must not be connected.
 Two essernet
®
-repeater allow a distance between two devices of max. 3000 m.
essernet
®
-module 500 kBd:

Use IBM cable Typ1 / 1A or similar, max. length 1000 m.
 Two essernet
®
-repeater allow a distance between two devices of max. 3000 m.
 Alternatively for distances of max 400m between two devices cable CAT 5 with shielding or similar may be
used.
7.1.9 Possible error sources
 Interruptions or interchanged connections in the essernet
®
connection line.
 Damaging the line (for the essernet
®
module 500 kBd) due to insufficient bending radii.
 Incorrect setting of the essernet
®
address on the DIL switch of the essernet
®
module (display: SYS fault.
essernet
®
cont: xx), yellow LED on the essernet
®
module is lit up.
 Loop is too long or attenuation too high. Typical loop resistances for loop lengths:
IBM cable approx. 100 ohms/km or transmission cable I-Y (ST) Y n x 2 x 0.8 mm approx. 70 ohms/km.
 The FACP or the unrecognised device is in emergency mode or is switching on, e.g. after a reset.
 FACP or essernet
®
device is not receiving any power or the connecting line is disconnected at both ends.
Error messages

The following states are reported only after the essernet
®
module has been restarted and are saved until the
next restart.
- Wrong address setting
- Hardware error
- Measuring mode
 The states >Communication fault<, >Short circuit/interruption< and >Normal operation< are not saved.
EMC fine protection
When using the essernet
®
micro module attention should be paid to the setting of the jumpers which
is required for the essernet
®
adjustment.
The overvoltage protection/the extended EMC protection must be produced using special protection
modules for the LAN cable. See fire detection technology product group catalogue.
