2.8 4-20 mA connection
2.8.1 Connecting the control signal
Remove the front cover and indicator.
(see page 15)
Terminal block(1) is now easily acces-
sible. Connect the cables to their
respective pole.
Maximum cable size AWG 13 (2,5 mm

)
2.8.2 Checking the control signal
The control signal can be checked
without having to break the signal loop.
This is done by connecting a low ohmic
ampere meter over the test points(2).
2.8.3 Bench test with the calibrator
When bench testing, it is possible to
connect the control signal (signal gen-
erator clips) to the two points(3), thus
eliminating the need for temporary leads.
2.8.4 Checking the IP internal circuit
With an ohm meter connected over the
two test points(3) it is possible to check
the IP’s internal circuit.
At room temperature the meter should
read ~150 - 200 Ohms. No reading indi-
cates an internal circuit break and the
IP converter needs replacement.
The IP converter is factory-
adjusted. No extra range or
zero adjustments are
necessary.
