Item Interface Description
5 “Power on” Green LED LED is on if supply voltage of signal electronics is present.
6
“Power Output not
active” Red LED Red LED is off if the switched output stage of the controller is enabled. If the LED is on, the
bearing and drive coils of the motor carry no current.
7 “RESET” Button
Reset button of the controller stage. The button is recessed and can be activated using a
small pointed object.
8 2- Digit Display “Speed” Rotational speed display in 100 RPM
9 “UP” Button Button for speed increasing
10 “DOWN” Button Button for speed decreasing
11 “Firmware” Label Firmware version and revision number
4.1.2 General Installation Instructions
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 48VDC). The usage of a galvanic
separated power supply, which is certified by a 3rd party (UL or CE), is highly
recommended.
WARNING
Hazardous voltage may be present.
The controller housing must be properly grounded and placed in a spill protected
environment. Use one of the DIN-rail screws on the back side of the controller
housing.
Do not use different and longer screws, which may result in short-circuits within the
controller.
1. The controller casing must be grounded. The screws of the DIN-rail bracket can be used for
grounding.
2. Connect the two motor connectors (“POWER OUTPUT” and “SENSORIC”) to the controller.
3. Connect the controller type specific connectors: see Section 4.1.3 for standalone operation with
the Standalone Controller.
4. The pump system requires 48 VDC supply voltage at a maximum power of 600 W. Depending
on the desired hydraulic operational point, smaller power supplies may be used. Also, a larger
supply may be used to power several pump systems simultaneously. Figure 12 shows the
power consumption depending on the pressure and flow rate. Contact Trebor for additional
information on a power supply solution.
5. Connect the DC power supply connector with the cable (included with the controller). Make sure
that the polarity is correct (see Figure 20) and that AC/DC power supply is off.
6. To secure the connectors, tighten all retaining screws according to the torque specifications in
Table 7.
4.1.3 Electrical Installation of Standalone Operation
For standalone operation, the controller is disabled when power is turned on. It can be enabled
manually by pressing
the “UP” button on the display. If the controller will be enabled automatically when
power is applied, the “ENABLE” pin on the “USER INTERFACE” connector (see Table 7) has to be
active (typically 24V).
