4.1.3 Installation Instructions for Power Supply
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 Error! Reference source not found.), which allows simple direct connection to t
he driver.
2. For other power supplies an open wire power cable for connection to the driver is specified in
Table 3 (cable type ICP-1.1). Depending on the required hydraulic operational point (see Figure
11), the pump system requires 24V with a maximum power of 35 W. At a lower performance
power supplies with smaller power or bigger supplies to supply several pump systems
simultaneously may be used. Consult Figure 18 to get the power consumption depending on the
flow. If other power supplies are used, than the one recommended 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 PLC Interface Signals
To operate the pump system with a PLC the analog input can be used to set the speed. The digital output
can be used to monitor the pump status and operating parameters (see Table 8).
The analog 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 Table 3
cable type ICS-1.2). Connect the designated PLC wires according to Table 8.
3. Follow Figure 22 as reference for hardware configuration of the PLC in/outputs.
4. Protect the un-used wires against short-circuit to each other
