Load Line

Load line (LdLn) is a manual offset to the control output (manual reset). The load line can be set from 0 to 100%. Load line must be set to zero when using ON/OFF control.

ON/OFF control

In ON/OFF control Output l is turned ON whenever the percent output exceeds l0% and Output 2 is turned ON whenever the percent output goes below -l0%. Therefore the proportional band is used to set the deadband. If the proportional band is set at 5% then an error of 5 will produce a l0% output; therefore, the deadband is

5.Reset and Rate would normally be set to zero; however, experimentation could improve the control response. Load Line must be set to zero.
