4.4 Test of Rotor-Card

The Rotor-Card should be electrically tested before you connect it to the rotator-control-box. Perform

the test as follows:

Connect the Rotor-Card to the ERC-M by use of the cable prepared in chapter 4.3

Connect 12V DC to the DC-connector of the ERC-M. The Rotor-Cards cannot work without

the external DC-supply.

- Measure the voltage between the test-points TP_GND und TP_+12V. You should measure

now the 12V. Also the polarity is very important. You should measure +12V at TP_+12V

against TP-GND. If the polarity is wrong, the Mini-DIN-cable is wired wrong.

- Now connect the ERC-M to the PC and start the Service-Tool.

- Press the Test-button of the Service-Tool.

- The relays of the Rotor-Card(s) will now engage in the following sequence in steps of 1

second: CW 1 / CCW 1 / CW 2 / CCW 2 / AUX 1 / AUX 2

4.5 Installation of the Rotor-Card into a control-box

Rotor-cards are to be mounted inside the control-boxes that don’t provide a remote connector.

Therefore you need to drill 3 holes in the housing of the control-box according to this drawing:
