The initial settings of the PWM basic parameter are made exclusively on the OEM
level.
Prerequisites
 Operating unit AZL2... for setting the parameters is connected
 Unit is wired up in accordance with the proposed application
 Mains voltage is available
 Safety loop is closed
 There is no heat request, unit is in standby (OFF)
 Fan parameters, such as maximum speed and Hall signal (number of pulses per
revolution) are known
 With unprogrammed program module (initial settings), AZL2... displays OFF UPr
 With unprogrammed program module (initial settings), the onboard operating panel
of the LME7... displays UPr
