Joystick answers vibration concerns
Thanks to a new four-way joystick recently introduced into the RMQ Titan range, engineers at Jones Engineering near Doncaster have significantly improved the control of their agricultural machine.
Smart look for panel-mounting controls
New additions to the popular Moeller RMQ-Titan range of control circuit devices include joysticks, four-way pushbuttons and selector switches.
Fitted to Moeller's FAZ miniature circuit-breakers and FIP residual-current circuit-breakers, the XFSM modules facilitate automatic restarting as well as local and remote switching.
In a great many industrial applications an uninterruptible power supply is an essential requirement because any disconnection in supply could cause expensive damage to equipment and lead to potentially hazardous situations.
Reliability can easily be affected even by the briefest external influences, particularly where residual-current protection is installed.

Small enclosures boast of big benefits
With high-quality construction and a host of design benefits, Moeller Electric believes its CI-K miniature enclosure range will have a major impact in the industrial housings market.
Miniature enclosure additions provide more choice
Moeller Electric claims the latest additions to its CI-K range of miniature enclosures make it the most comprehensive range of enclosures of this type available on the market.
The XFSM is the ideal device to automatically check whether or not a disconnection has been caused by a continuing fault.
It carries out a predetermined number of automatic restart attempts.
Thus, operational continuity can quickly be restored, where the failure was just a "blip", removing the need to keep "a person on site" together with the associated time and money costs.
Connected to a PLC module or Moeller's Easy control relay, the XFSM allows the user to easily control what should happen after a fault occurs.
In the case of a continuous fault current the FIP trips out immediately and at each attempted restart remaining in the Off position after the final one.
Then the remote switching module generates an alarm.
In conjunction with the FIP-XPM test module the remote switching module can additionally be used for remote testing of residual-current protection devices according to the Standard.
For security purposes XFSM modules can be mechanically interlocked and sealed.
LEDs indicate the operational and alarm status.
The mechanical switching capacity of the unit is up to 80A for four pole RCDs, providing a mechanical/electrical lifespan of 10,000 switching operations.
Fed with a rated operating voltage of either 24-400V AC or 24-80V DC, power consumption is 5W.
Users have the choice of operating the module in a number of different modes: stand-alone, remote control, and remote control plus a specific number of automatic reset attempts after a fault.
The rated voltage for the control inputs varies between 24 and 230V AC/DC, while the relay output for a tripping test is 400V AC.
XFSM modules provide a terminal capacity of either 2 x 1.5 or 1 x 2.5mm2.
The FAX-FIP-XFSM is part of Moeller's extensive range of miniature circuit breakers.
Offering types with B, C, D, S and R characteristics Moeller has an MCB for virtually every application around the world, from cable and device protection to the protection of complex control circuits.
