General safety instructions
IMPORTANT
Install the equipment so that the power supply for the controller
never falls below the minimum! A power supply that is too low
causes errors in measured values and can lead to over metering
in a control system!
The sensor PER is a sensor with a passive 4-20 mA two-wire
interface. The power is supplied externally or from a measuring and
control system. Connection to the DULCOMETER
from ProMinent ensures automatic compliance with interface safety
requirements.
Additional safety instructions for operation with external
equipment:
IMPORTANT
• Connection of the sensor to external equipment after
authorisation from ProMinent!
• The power supply for the sensorl may not fall below 16 V DC,
even for a short period! The power source must have a
minimum load rating of 35 mA at a minimum of 16 V DC. A
power supply that is too low causes errors in measured
values and can lead to dangerous over metering!
• The sensor is not electrically isolated. In order to
avoid any disruptive compensating current, the external
equipment and any other loads connected to the power
supply must be electrically isolated.
Observe the following when connecting to external equipment:
Power source: 16-24 V DC, min 35 mA at 16 V DC
Max load: 1.0 W
IMPORTANT
When electrically connecting the sensor to the measuring
equipment, only use signal cables with a diameter of 4 mm (see
section 15, Ordering information).
Turn the upper section of the sensor anti-clockwise through 90
and remove.
Strip the outer insulation back by about 5 cm so that both con-
nectors are visible.
