In the “Mode Signal contact” box, you select the “Monitoring correct
operation” mode. In this mode, the signal contacts monitor the functions
of the device, thus enabling remote diagnosis.
A break in contact is reported via the potential-free signal contact (relay
contact, closed circuit).
X Loss of the supply voltage 1/2 (either of the external voltage supply or of
the internal voltage).
1
Select “Monitor” for the respective power supply if
the signal contact shall report the loss of the power supply voltage, or of
the internal voltage that is generated from the external power supply.
X One of the temperature thresholds has been exceeded (see on page 19
“System Data“). Select “Monitor” for the temperature if the signal contact
should report an impermissible temperature.
X Removing a module. Select “Monitor” for removing modules if the signal
contact is to report the removal of a module (for modular devices).
X Fan inoperable (for devices with a fan).
X The removal of the ACA. Select “Monitor” for ACA removal if the signal
contact is to report the removal of an ACA (for devices which support the
ACA).
X Non-matching of the configuration in the device and on the ACA
2
. Select
“Monitor” ACA not in sync if the signal contact is to report the non-
matching of the configuration (for devices which support ACA).
X The inoperable link status of at least one port. The reporting of the link
status can be masked via the management for each port in the device.
Link status is not monitored in the state on delivery. Select “Monitor” for
bad connections if the signal contact is to report an inoperative link status
for at least one port.
X If the device is part of a redundant ring: the elimination of the reserve
redundancy (i.e. the redundancy function did actually switch on), (see on
page 161 “Ring Redundancy“). Select “Monitor” for the ring redundancy if
the signal contact is to report the elimination of the reserve redundancy in
the redundant ring.
Default setting: no monitoring.
1. You can install additional power supplies in a MACH4000 device, which
the device reports as P3-1, P3-2, P4-1 and P4-2 in its user interfaces. You
will find details on the power supplies in the document Installation Guide.
2. The configurations are non-matching if only one file exists or the two files
do not have the same content.
