PWMs Retransmits
PWM Retransmit Folder
The PWM Retransmit feature is similar to the
Analog Retransmit except the output is modulated
by varying the Pulse Width, thus the term Pulse
Width Modulation. This is also known as Time-
Proportioning.
To configure the outputs, press the
SETUP button
on the Synergy Controller touch screen and go to
the
SETUP\Special Functions\PWM Retransmits. .
Select the PWM Retransmit 1 folder to open the
data output mapping options.
The parameters for each PWM are :
♦
Retransmit Source
♦
High Eng. Scale
♦
Low Eng. Scale
♦
High Duty Cycle
♦
Low Duty Cycle
♦
Cycle Time
The Retransmit source is typically one of the PID
Variables; i.e. Channel 2 Heat PID Outputs.
On/Off Retransmits
The parameters for each On/Off are :
♦
Retransmit Source
♦
High Eng. Scale
♦
Low Eng. Scale
♦
Hysteresis Value
♦
Low Duty Cycle
♦
Active State
The Retransmit source is typically one of the PID
Variables; i.e. Channel 2 Heat PID Outputs. The
output is Active when the Retransmit Source
Variable is between the High and Low Eng. Scale
limits.
