Page 19: Calibrate - Step 3 - Rotacheck Basic
4 Installation 4.9 Calibrate - step 3 - Rotacheck Basic Step 1 The Rotacheck Basic must be fully installed: - Mechanically - Electrically The unit will flash green on power up and perform an internal calibration after 5 sec. The unit is ready to use when the green LED lights steadily. -
Page 20: Calibrate - Step 3 - Rotacheck+ (With Teach)
- A red LED is flashing to indicate TEACH ongoing - Let the cleaning process run for at least 16 minutes (the Rotacheck+ will teach-in cleaning pattern during this time) - Every sensor hit during TEACH is indicated by a yellow LED flash - Rotacheck+ will light up green when teach-in is finished The TEACH sequence is terminated if no sensor hits are registered within a 4 min. - Page 21 - If parameters are within the calibrated values, a “Rotation OK” feedback is initiated - If parameters are outside the calibrated values, the alarm function is entered. NOTE If it – due to special circumstances - proves too difficult to make a proper calibration, Rotacheck+ can be reset to “1 power up mode”.
- Page 22 Feedback test mode is a function that can be enabled after installation to validate proper function of the external wiring. When the mode is entered, Rotacheck+ automatically switches PLC and LED outputs in 5 seconds intervals. Enter Feedback test mode: Press the blue button on the sensor board and release after 5 seconds when 2 Yellow LED flashes are seen.
