ATTENTION
Always use two separate transformers: one for the sensor and one for the
controller.
6. Close the enclosure and fix the cover.
7. Switch on the power supply.
ATTENTION
Do not exceed the maximum power supply rating! Measure before installation!
Unregulated 24 VAC supply units provide higher nominal output voltage and
activate the integrated fuse protection.
ATTENTION
If a G‑type article is using the same AC power supply source (transformer) as
F‑type article, a SHORT CIRCUIT may result when the power supply and analogue
signal terminals are connected to the same common ground! In this case always
connect different article types to separate AC transformers or use the same
article version.
8. Customise the factory settings to the desired ones, through 3SModbus software
(if necessary). For the default factory setting see
Table Modbus register maps .
NOTE
When you start autotune function, check the status of holding register 20 to know
when it finishes.
