5 SETTING AT WORK
Make sure that the use of the instrument does not exceed the intended use (i.e. pressure and temperature values and the
like) and ensure the measurement made is correct by changing a few times the level of the fluid in the vessel.
If this cannot be done, you can move the float by hand.
As far as the
version with transmitter is concerned
, series connect an ammeter in the line to check it for proper
operation.
The standard setting ranges from 4mA = 0% to 20mA = 100% (on request, the setting can be reversed).
Comply with the power supply value 10-35 Volt for standard models and d10-28 Volt for explosion-proof models.
The maximum load is given by the following formula:
R
LOAD
= (V
SUPPLY
– 8) / 0.023
The instrument shall never work close to strong magnetic fields (minimum distance: 1 m)
It can only be used with special feeders or indicators.
As far as the
version with alarms
is concerned, check the alarms for proper operation by making the float slowly slide
along the rod to make sure the alarm switching takes place.
6.CALIBRATION
Adjusting the pointing head
Make sure the float is in the “minimum level” position, then remove the front lid and loosen the hand fastening screw
located beneath the latter. Align the hand on the “ZERO” or minimum level position if other than zero); tighten the
locking pins taking care not to damage the hand.
IN the models equipped with two hands, (RED HAND = metres and BLACK hand = centimetres), in tightening the
locking pins, take care to maintain the hands on the fastening pin correctly spaced from one another, to prevent them from
locking out while turning.
