Voltage Setting

The LMS-D6 is provided with an auto-seeking power supply, and therefore requires no external adjustment for correct operation with international AC line voltages ranging from 60 to 250 volts.

Safety Earthing

The green/yellow wire of mains cord must always be connected to the electrical installation's Safety Earth or Ground. It is essential for personal safety, as well as proper operation of the unit.

The green/yellow wire is internally connected to all exposed metal surfaces. Any rack framework which this unit might be mounted into is assumed to be connected to the same grounding circuit. The LMS-D6 has balanced audio connections and does not require disconnection of this or any other safety earth for the avoidance of hum loops. If any problems are experienced with hums or buzzes, careful attention to the signal cable grounding will effect a cure.

AC Power Fusing

The incoming mains power fuseholder is mounted on the rear panel. If the fuse needs to be replaced it must be properly rated as follows: 20mm 1A 250 V type T. It is important for continued safety that this specification is adhered to. It is very unlikely that this fuse will fail during normal use, and such a situation must be treated with some caution as to the cause.

Powering Up

When the LMS-D6 is switched on by operating the power on-off switch located on the rear panel, the internal circuitry carries out a series of routine diagnostic tests.

After the switch-on cycle, the screen will revert to displaying the delay program name that was in use when the unit was last powered down.

The internal memory automatically saves all settings when the unit is switched off, so there is no need to re-load delay and temperature information every time the system is powered- up. The memory contents are retained indefinitely without the need for an internal backup battery.
