Temperature
monitoring
The optional temperature module enables heat build-up to be monitored
within the rack or special “hot spots” such as cooling plates on servers.
Up to 5 external temperature sensors type TS-1 can be installed as part
of the temperature module. These can be attached to the components
being monitored with cable straps or adhesive pads.
Via the diagnostics tool alarm thresholds can be set for individual tem-
perature alarms and forwarded via the programmable relay contacts. The
settings via the diagnostics tool are described in more detail in the com-
missioning chapter.

Device
shutdown
The extension module type SU-1 enables external equipment to be shut
down via a type SR-1 shutdown relay.
Equipment with a power rating of up to 400 W for inductive loads and up
to 2,000 W for resistive loads can be shut down via the relay contact. A
suitable high power relay should be activated via the shutdown relay for
equipment with higher power consumptions. Schematics for the shut-
down relay and the high power relay is described in more detail in section
5.2.12 or 5.2.13 “Installation / TITANUS

down“.
4.7 Door contact switch
Cabinet doors can be monitored with door contact switches for supervi-
sion. This is especially required if the TITANUS
RACK·SENS
®
1U is trig-
gering an optional extinguishing system. Door contact switches are to be
positioned in such a way that the switch is activated when the door is
closed and the contact is closed. If the door is opened, the contact in the
switch opens and the TITANUS
RACK·SENS
®
1U device is blocked. Af-
ter a delay of 10 seconds, the TITANUS
RACK·SENS
®
1U device indi-
cates a fault. If several door contact switches are connected to the door
contact input, they are to be connected in series, so that the TITANUS
RACK·SENS
®
1U
device is interrupted at the door contact switch input if
only one of the doors is opened.
