Steel grid resistors for marine applications

Propulsions that enables ship movements are electronic systems. High energy capacity is required while large masses are moved. The energy which is accumulated in braking can be converted into heat by steel space resistors. This is reliable, cost-effective and safe solution.

PL e -level safe signal transmission up to 800 m according EN ISO 13849-1

Wireless DOLD UH 6900 can be used for safety applications up to Cat. 4 / PL e or SIL 3 -level. Bidirectional radio controlled safety system UH 6900 from the SAFEMASTER W series, is for protection of hazardous areas. Two safety zones can easily be connected wirelessly over a considerable distance. The main application areas include applications covering large areas and mobile applications such as fully automated driverless transport systems.

Simple and inexpensive retrofitting of existing safety systems can also be achieved wirelessly with this system. The device allows connection of up to 3 two-channel safety transmitters, simple configuration, and comprehensive sampling and diagnostic options.

Reliable safe position detection for maintenance doors and hatches

CES is PL e-safety level non-contact safety switch. It is RFID coded and it can be used for monitoring gates and doors of production area. With wide range of operating temperature (-40 … +65 °C) CES-C02 is suitable solution for challenging outdoor applications due to its frost resistance.

Key transfer systems for rugged outdoor environments

The key transfer system combines the advantages of none wiring, mechanical safety with electrical safety. Modular interlocking system STS is type-tested in accordance with the legal requirements and is suitable as a stand-alone system for use in safety applications up to Cat. 4 / PL e in accordance with EN ISO 13849-1 without fault exclusion.

Mechanical coding and robust stainless steel construction is especially meant for use in extreme ambient temperatures or hostile conditions, e.g. dust, moisture, dirt, etc. While all locking units of the system can be built as fully mechanical key transfer system is optional solution for ex. outdoor uses such as harbor areas. As a result, large number of difficult dangerous applications can be safeguarded by using DOLD STS key transfer system.

The ADMIRAL AX, VISION VX and DUAL BEAM standard light curtain models are available with pre-installed IP67 WaterTIght cases as well as heating systems that provide use in challenging outdoor conditions.

There is available e.g. Heated version of WTHF with an operating temperature range up to -25 ° C. The WaterTigh cases are suitable for light curtains with 2, 3 or 4 beams and a protected height of 1660 mm and 1810 mm with a resolution of 30 mm.

Dual Beam -safety light curtains for access control are shielded with double beam.

Each beam consists of two parallel beams which both have to be interrupted in order to activate the safety function. Due to the dual beam system the light curtain is not interrupted by small objects as birds. The maximum operating range is up to 80 m, which makes it suitable for long distance access control . For the outdoor use the curtain is available with heated IP 67 WTH case.

Starting dangerous machine movements is not possible when CKS key is withdrawn

CKS is based on transponder technology and prevents the installation starting when the key is removed. The CKS is used as an electronic LOTO (Log out tag out) mechanism and for safely entering installations for ex. during maintenance or cleaning. The system can also be converted to electrical key transfer system with two CKS key readers.

The measurement in 3-phase or single-phase systems is very simple without extensive wiring.

The universal MK 9300N series monitor up tp 9 parameters simultaneously. These are under-, over-voltage, voltage range, voltage asymmetry, under-, overcurrent, cos phi, effective-, apparent- and reactive power, frequency and phase sequence. The relay can also be used to monitor single-phase systems. The MK 9300N meets all the safety, performance and quality requirements of DNV-GL and is therefore certified as seaworthy.

Monitoring of insulation resistance of ungrounded voltage systems to earth in marine applications

In the marine industry safety and monitoring of the insulation level of the electrical networks is critical. Failures during ships travel are difficult to repair and cause potential dangers.

Insulation monitor offers a convincing solution for insulation monitoring of non-earthed power supplies in ships. It can avoid the risk of fire and accidents due to slowly evolving insulation faults. Faults are detected even during operation and costly plant standstills are prevented. Two limits can be set for the insulation monitor; alarm and shut down.

Current monitor offers a convincing solution for insulation monitoring of earthed power supplies.

It can avoid the risk of fire and accidents due to slowly evolving insulation faults. Faults are detected even during operation and costly standstills are prevented. Two limits can be set for the current monitor; alarm and shut down.

In the shipping industry, the safety of electrical devices is absolutely essential, as disruptions during shipping are difficult to fix at sea and they can cause hazardous situations.

The ship electrical networks are often non-earthed and can be monitored by insulation monitors. The insulation level can be unobtrusively damaged over time, for example as the conductor insulation weakens. Two limits can be set for the monitor; alarm and shutdown. The growing problem can be located and fixed before standstill. The closing signal of the insulation monitor acts as a safety factor in cases where the damaging of the insulation has not been detected in time or the linsulation evel drops quickly.
