2. Connect the flow sensor link cable to ABCDE
⏚
terminals. (Not applicable for compact version, where the sensor was
connected in factory).
Terminal blocks on the sensor and on the electronic unit are labeled identically, so terminals A - A, B -B, C - C, D - D, E - E,
⏚
- GND have to be interconnected. Connect the shielding of the link cable only on the side of the sensor to the ground
terminal on the terminal block of the sensor. Standard length of the link cable between the sensor and the electronic unit
is 6 meters. The link cable is included in delivery. The standard length of the interconnection cable between the sensor
and the electronic unit is 20 feet. The interconnection cable is included as standard with the product.
Maximum length of the link cable is 82 feet (optional). The link cable should be always connected before the power
supply is connected to the transducer.
If the power cable has already been connected to the transducer, connecting and disconnecting of the link cable when
the transducer is under voltage is prohibited.
3. The induction flow meter is powered by mains voltage 230V / 60Hz connected to the power supply terminal block
labelled as
L - PE - N
, or by low voltage 12 VDC or 24 VAC connected to terminals labeled
L - PE - L
.
The polarity of supply conductors makes no difference in case of using the 12 V DC power supply.
Connect the power cable to the terminals.
The induction flow meter does not have its own ON-OFF switch, so it must be fused and switched ON-OFF in another
device, such as a switchboard.
The protection of electric circuits is ensured by protective fuse T100mA, or 1A for the 12 - 24 V version, located next to the
power terminals.
Switch power supply on only after the sensor link cable and external device signal cables are connected!
4. Connect external devices that utilize current output or pulse outputs to terminals
BIN1
,
BIN2
, and
ANAL
. All outputs are
isolated.
