Munters 1 RSU-2 Platinum Pro Manual

Munters 1 RSU-2 Platinum Pro Installation Guide

Munters’ RSU-2 enables long distance remote scale/feed bin weighing and calibration, managed via the Platinum Pro/Rotem One.

• Each RSU-2 supports two weighing devices.
•  Each Platinum Pro supports:
  •  up to two RSU-2 units (Version X.17 and below)
  •  up to five RSU-2 units (Version X.18 and above)

Controller – RSU-2 Wiring

• RSU-2 requires RS-485 infrastructure.
• Platinum Pro – RSU-2 installations support a daisy chain only.
  Employing a Munters HUB-4 enables star configuration installations. Refer to the HUB-4 manual.
•  Install a 120-ohm termination unit on the last RSU-2 in the chain. Failure to install a terminator results in a non-functional system!
• Apply 24VAC from an independent power supply.
• Wiring requirements:
  •  RSU-2 – Controller wiring: Shielded 22 AWG. Maximum distance: 200 meters/650 feet.
  •  RSU – power supply wiring: 0.75 mm2 , 2-wire

CAUTION    To ensure interference and lightning immunity, use shielded cable only (22 AWG minimum)!

CAUTION    Power and signal wires must be in separate cables.

2 Using the RSU-2

The following section describes how to use the RSU-2.
Wire each RSU-2 to the Platinum Pro before beginning.

Configuring the RSU-2

1. On the RSU-2, press down the Select button until Addr appears.
2. Press each arrow key to define each card as Card 1 or Card
3. In the Platinum Pro, go to Scale > Scale Layout.

For each RSU-2, map the channel to the address that you defined above.

Viewing the RSU-2 Data

• The RSU-2 screen displays:
  
  •  The weight of the last bird weighed (connected to bird scale)
    
  •  The current amount of feed in the silo (connected to a silo).
    
  •  0.00 (card address not defined)
