Preliminary Steps - Mettler Toledo PE360 DeltaRange Instrucciones De Manejo

PRELIMINARY STEPS: Checking and correcting the voltage setting
The voltage set in the balance must agree with the power-line voltage.
Before putting the balance into operation for the first time, the voltage setting should be cheked and, if needed, corected.
The voltage set at the factory is listed on a label on the power connection socket (5).
If this voltage setting corresponds to your local power-line voltage, go on the next page.
If this voltage setting does not correspond to your local power-line voltage, or if the label is missing, the balance housing must be opened, the voltage set on the
voltage selector must be cheked, and if necessary, changed.
Opening the housing
Before doing so, make sure that the power-line
cable is disconnected!
When the power-line cable is connected, the balance
electronics are powered, even though the display
does not light up!
– If the weighing pan (6) and pan support (7)
are installed, remove them.
– Remove screw (8).
– Carefully remove housing cover (10) with in-
use cover, if installed.

Voltage selector next to weighing cell
– Check whether the voltage selector jumper
(11) is plugged onto the pin that is labeled
with your local power-line voltage.
– If necessary, change position of voltage
selector and plug it onto the cprrect pin.
Admissible power-line voltages:
95 V, 105 V { Install 125 mA slow
110 V, 120 V {blowing microfuse
190 V, 210 V { Install 63 mA slow
220 V, 240 V { blowing microfuse
Note: When switching the operating voltage from
95...120 V to 190...240 V (or vice versa), the
microfuse must be changed. The two jumper plugs
(12) must not be changed.
Closing the balance housing
– Carefully set the housing cover (10) down onto
the balance.
– Insert screw (8) and tighten.
Installing the weighing pan
– If still in place, remove protective coating from
weighing pan.
– Place the pan support (7) onto the conical peg
(13).
– Place the weighing pan (6) on the pan
support.
Connecting the power cable (14): see next page
under "Balance location".
