5) TRIAC TC OUTPUT
In certain models, the device has a high voltage Triac output which is typically used for piloting the fans/continuous
compressors.
The output can be configured for proportional operation (constant speed variation) or as ON/OFF; If configured as a
proportional output, the phase parameters and the pulse length of the Triac must be properly configured for better
adaptation to the load characteristics.
Parameter Description M.U. Min Max
CF33 Enable analogue TC output num 0 1
CF36 Analogue TC output phase shift num 0 90
CF39 Analogue TC output pulse length (1 unit=69.4 μs) num 5 40
CF42 Analogue TC output configuration num -24 26
Note: Parameters CF36 and CF39 have a meaning only if the outputs have been configured as Triac outputs.
Parameter CF33
Allows the Triac analogue output to be characterised in the following manner:
Value Type Description
0 None Output disabled
1 Triac Output configured as Triac
Parameter CF36
Indicate phase shift values to pilot Triac with phase cutting in the event of inductive loads; the value to enter
represents the phase shift angle between voltage and current of the motor connected to the output (obtained from
the cos indicated in the motor specifications).
Parameter CF39
Indicate pulse length to pilot Triac (1 unit = 69.4 μs).
