4.1.3 Installation Instructions for Power Supply
!
WARNING
Hazardous voltage may be present.
Always isolate the electrical power supply before making or changing
connections to the unit.
In case of the usage of an inadequate AC/DC power supply, mains
voltages may be present (even if the system is designed for 24 VDC).
The usage of a galvanic separated power supply, which is certified by a
3
rd
party (UL or CE), is highly recommended.
1.
A certified and tested desktop power supply with a specific connector is available as an accessory
(see
), which allows simple direct connection to the driver.
2.
For other power supplies an open wire power cable for connection to the driver is specified in
ICP-1.1
). Depending on the required hydraulic operational point (see
), the flow control system requires 24 VDC with a maximum power of 35 W. At a lower
performance power supplies with smaller power or bigger supplies to power several flow control
systems simultaneously may be used.
Consult
to get the power consumption depending
on the flow.
If power supplies are used other than the one defined by
Levitronix
®
, it is highly
recommended to test these under dynamic conditions (acceleration and braking of the pump rotor
speed).
3.
Make sure that the polarity is correct, and that AC/DC power supply is off.
4.1.4 Installation of Flow Sensor
See
Section 4.4
4.1.5 Installation PLC Interface Signals
To operate the flow control system with a
PLC
the analog input can be used to set the flow or speed. The
digital output can be used to monitor the pump status and operating parameters (see
CAUTION
The analog input is not galvanically isolated from the controller
electronics. To avoid ground loops and malfunctions, use
floating analog signals.
1.
Power off the system.
2.
A signal cable with driver connector is available to simplify PLC wire connections (see
cable type
ICS-1.3
). Connect the designated PLC wires according to
3.
Follow
as reference for hardware configuration of the PLC inputs and outputs.
4.
Protect the un-used wires against short-circuit to each other
