CONFIGURATION PARAMETERS
Note
(*) = it depends on input type; the parameter must be set according to hardware factory setting.
(1) = configuration parameter present at Level 1.
(2) = this parameter controls the device operation at switch on after a power supply failure during “START” status: if this parameter is set to 0,
the operation of the control unit depends on the duration of power supply failure (see section “OPERATION”); vice-versa, if the parameter
is set to 1, the control unit restarts in “START” status.
(3) = this parameter defines the buzzer signal duration when the Melt threshold or the operating setpoint has been reached: if it is set to 0 there
is no buzzer signal; vice-versa, if it is set to –1 the buzzer signal continues until it is manually switched off.
