Text for tenders: Monitoring set climate control equipment


Monitoring set climate control equipment

The set "monitoring climate control equipment" contains

all the necessary modules for monitoring of Rittal

TopTherm (RTT) cooling units with Comfort controller.

Temperatures, messages, alarms, etc. can be displayed

directly in intranet resp. internet on the web surface.

Trap alarms are sent automatically to connected SNMP

network management systems. SMS text messages are also

possible optionally via the Rittal GSM module.



The set is consisting of:



- Processing unit PU with firm/ software for

applications with climate control equipment.

- Interface card climate control unit RTT I/O unit (SK

3124.200)

- Power pack 24 V DC, input; 100 . 240 V AC ( DK

7320.425 )

- Connection cable D with IEC320 connector ( DK

7200.210 )

- Cat5 connection cable, 2 m

For connection RTT I/O unit to processing unit PU

- Data cable RS232, 2 m, for connection of RTT I/O unit

to RTT climate control unit with Comfort controller



Extension/ Configuration



The processing unit PU has 4 channels for 4 interface

cards Climate control unit RTT I/O. A RTT I/O unit is

enclosed with the set. Therefore, up to 3 RTT I/O units

can optionally be extended. Each RTT I/O unit can

monitor one Master TopTherm cooling unit with 9 slave

climate control units. With the set up to 10 cooling

units can be monitored, with extension max. 40 cooling

units.

Instead of the interface card also the sensor units of

the CMC-TC monitoring system can be connected.

Therefore, additionally smoke, air humidity, air flow,

enclosure access can be monitored.
