Climate control accessories Control/regulation Control unit for For filter fan Part No. EC fan-and-filter unit 3245.XXX 3235.440 Temperature-dependent speed control for EC filter fans to reduce noise and save energy. – Status LED to display the operating status The function of the fan can also be monitored. – Alarm relay for reporting overtemperature, fan – Activation and monitoring of up to 4 EC fanand- defect, cable interruption and sensor failure filter units (caution: EC fan-and-filter units cannot be controlled with speed control Configuration: 3120.200) NTC sensor, length 71” (1800 mm) – Rated operating voltage: 24 V (DC) – Top-hat rail assembly – Temperature setting range: 41° to 131° F (+5° to +55° C) – External temperature sensor to record the ACTUAL temperature Speed control Packs of Part No. Temperature-dependent speed control for 1 3120.200 TopTherm filter fans and air/air heat exchangers for noise reduction and to save energy in part- load operation. Configuration: − Speed control Technical specifications: − NTC sensor, length 71” (1800 mm) − For mounting on a 35 mm support rail Note: DIN EN 50 022 − Dimensions (H x W x D): Only suitable for use with 1-phase AC motors and 4 x 4 x 2 (90.5 x 105 x 60.2 mm) equipment. − Rated operating voltage: 100 – 230 V (AC) Accessories: − Setting range: Mounting panel TS with integral top-hat rail, +68° to +131° F (+20° to +55° C) − Phase cross-over with microcontroller see page 665 − Maximum fan output 300 W or 2 A Interface board Packs of Part No. for equipment with e-Comfort controller 1 3124.200 The interface board is an extension for equipment with e-Comfort controller to monitor a master/ range power pack 7320.425 (100 to 240 V (AC), slave combination of up to 10 cooling units 50/60 Hz) or externally via a Kycon connector. in conjunction with a Rittal CMC III. Control is achieved via standardized interfaces: RS232 Configuration: (DB9) or RS485, one PLC interface (DB9). RS422 − Interface board integrated into a plastic box (RJ 45 jack) is the connection to the Rittal CMC H x W x D inches/U (mm): 1 U x 5 x 5 (1 U x 136 III. This allows remote monitoring via TCP-IP, with x 129) graphical interfaces for operation, evaluation − Serial SUB-D cable, 59” (1500 mm) and control, documentation, and connectionto additional sensors for access control. The extension board is built into a 1 U plastic housing. A voltage supply of 24 V (DC) is required. This may be supplied from the CMC III via a wide- SK bus system Packs of Part No. The SK bus system facilitates communications 1 3124.100 between several enclosure cooling units and air/ water heat exchangers .500/.510/.540/.600/.610/ 35C .640. via a master/slave construction such as that Note: 25C required e.g. in complex bayed enclosure − n = n – 1 20C systems for optimum operating conditions. − nB: Number of order units (SK bus system) 30C 20C 40CKB − n : Number of cooling units to be linked K Technical specifications: 35C The master/slave construction facilitates common activation and deactivation via door limit switches, parallel activation and deactivation via a temperature setpoint, and common collective fault signals and temperature logging, thereby eliminating the need for intricate wiring. Configuration: − 118” (3 m) shielded interface cable − Operating instructions on programming the cooling units Rittal Catalog 33/Climate control Metric measurements for are exact, imperial measurements are rounded 477
