Monitoring the safety door on a injection moulding machine
Advantages / Customer benefits:
Compared to solutions with time-controlled unlocking of the protective door, the sensorless standstill monitor LH 5946 can minimise maintenance and set-up times, thus increasing productivity. Furthermore, with a conventional protective door release via a time control, the dangerous movement cannot be necessarily excluded.
The minimal effort required for installation and commissioning also makes the device ideal for retrofitting measures in existing systems.
- For safety applications up to cat. 4 / PL e / SIL 3
- Fast reaction time
- Easy commissioning by means of screwdriver
- Easy retrofitting, as there is no connection of sensors
- 2-channel safety monitoring with extended error diagnosis
- Reductions of down time of machines and installations
- Combinations with safety lock SAFEMASTER STS available
Potential fields of application / Target group:
- Plastics and rubber machines
- Machines and plant building
- Woodworking
- Machine tools
- Conveyors
- Steel plants
Further products of the SAFEMASTER S series:
The SAFEMASTER S series offers even more solutions for safe standstill and speed monitoring of drives:
- The safe sensorless standstill monitor UG 6946 with a width of only 22.5 mm can be installed even in difficult spaces in the switch cabinet, as well as in retrofitting and upgrading.
- The safe speed monitor UH 6932 offers convenient speed monitoring via PNP or NPN initiators as well as simple and time-saving commissioning without a PC.
- The sensorless speed and frequency monitor UH 6937 now offers safe monitoring of the phase sequence and direction of rotation of 3-phase AC motors.
- The safe speed and standstill monitor UH 5947 covers the combined application of encoder signals and PNP or NPN initiators. An alternative device variant enables the use of NAMUR sensors.
