P22 Delay Angle
Range: 0 to 146.76 degrees Default: 146.76° Scaling: n/a Type: R
‘Firing Delay Angle’ shows the firing delay angle (thyristor off time).
P23 Max Angle
Range: 17.27 to 146.76 degrees Default: 57.554° Scaling: n/a Type: R
‘Maximum Optimizing Delay Angle’ shows the maximum allowed Firing Delay Angle during
optimizing. (The Optimize function reduces energy consumption by reducing voltage, but the
system also senses motor conditions and automatically adjusts the maximum delay angle by which
the voltage can be reduced without allowing the motor to stall.)
P20 Reference PF
Range: 0 to 146.76 degrees Default: 146.76° Scaling: n/a Type: R
‘Reference PF’ shows the Power Factor Angle that the SR44 has calculated as the target for the
optimizing control loop. (Refer to Ch 3.6 for PF degrees-to-ratio conversion.)
P21 Internal PF
Range: 0 to 146.76 degrees Default: 146.76° Scaling: n/a Type: R
‘Internal PF’ shows the Power Factor Angle of the load.
(Refer to Ch 3.6 for PF degrees-to-ratio conversion.)
User-supplied current transformer is required if any of the current- and power-related monitoring features
are needed in bypass mode. Refer to Electrical Installation Chapter 2, sections 2.4.1 & 2.5.2 for details.
