Load feeders with soft starters Soft starters can also be used to prevent current peaks in the line supply instead of the Wye-Delta starting combinations. Three versions of these soft starters are available:
SIMOCODE pro ■ SIMOCODE pro C, basic unit 1 PROFIBUS DP interface, 12 Mbit/s, RS485 4I/3O freely as- signable, input for thermistor connection, monostable re- lay outputs ■ 3RW30 ■ 3RW40 ■ 3RW44 - 24 V DC 3UF7 000-1AB00-0 - 110 ... 240 V AC/DC 3UF7 000-1AU00-0 The 3RW4 soft starters come as standard with an integrated solid-state overload relay. This means that, in fuseless combi- nations, a motor starter protector is only required for short-cir- cuit protection. In the case of 3RW30 soft starters, the motor starter protector must also cover the overload protection.
■ SIMOCODE pro V, basic unit 2 PROFIBUS DP interface, 12 Mbit/s, RS485 4I/3O freely as- signable, input for thermistor connection, monostable re- lay outputs, can be expanded by expansion modules - 24 V DC 3UF7 010-1AB00-0 - 110 ... 240 V AC/DC 3UF7 010-1AU00-0 3RB22/23 overload relays and SIMOCODE pro The modular, solid-state overload relays with external power supply type 3RB22/23 for high-feature applications up to 630 A have been designed for inverse-time delayed protection of loads with normal and heavy starting against excessive tem- perature rises due to overload, phase unbalance or phase fail- ure.
■ Connection cable - 0.1 m, flat 3UF7 931-0AA00-0 - 0.3 m, flat 3UF7 935-0AA00-0 - 0.5 m, flat 3UF7 932-0AA00-0 - 0.5 m, round 3UF7 932-0BA00-0 - 1.0 m, round 3UF7 937-0BA00-0 - 2.5 m, round 3UF7 933-0BA00-0 SIMOCODE pro is the flexible, modular motor management system for motors with constant speeds in the low-voltage performance range. It provides the intelligent, communica- tion-capable interface between the higher-level automation system and the motor feeder. ■ For other accessories and software for SIMOCODE pro see Catalog LV 1 Chapter 7.
A configuration with 3RB22/23 overload relays and with SIMOCODE pro requires in each case a basic unit, a connection cable and a current measuring module. The MLFBs of the cur- rent measuring modules are listed in the tables. Details of the basic units and connection cables are given in the following: 3RB22/23 ■ Basic unit (=evaluation module) - Monostable, screw 3RB22 83-4AA1 - Bistable, screw 3RB23 83-4AA1 - Monostable, spring-loaded 3RB22 83-4AC1 - Bistable, spring-loaded 3RB23 83-4AC1 Introduction 9
