7.1 What is to be done if? (continued)
7.1.8 Load is not lifted
• SLE21 load monitor / SMC21 Multicontroller has been actuated or is faulty.
1. Check setting, see page 46.
2. Actions for SLE21 / SMC21
LED I...III "on" and LED err => error.
Actions to eliminate an error may only be performed by trained personnel.
Error specification - Sensor current <1 mA or > 24 mA
Elimination of error - Check voltage supply
- Check sensor current (terminal 21)
- Check sensor cable
- Replace sensor
Error specification - Overload
Elimination of error - Remove load from hoist
Error specification - Overtemperature (hoisting motion not possible)
Elimination of error - Allow motor to cool down - check PTC thermistors
Error specification - Control error
Elimination of error - Check wiring
(lifting terminal 3 and lowering terminal 4 are activated
simultaneously)
Error specification -System error
Elimination of error - Check voltage (terminal 6)
- Switch SLE21 / SMC21 off/on
- Replace SLE21/SMC21
