    GLOSSARY Set point (set or operating point) • The set point is the value at which the appliance has to intervene to maintain the measurement controlled at the required level. Differential (or hysteresis) • The differential is the maximum permitted variation from the set point for the measurement controlled prior to the intervention of the appliance.
  • Page 9 PWM operation (in proportion to time) • This is a neutral zone type of operation in which the relays are activated periodically in impulse mode PWM Mode (the interval can be set, see the output menu). The PWM procedure modulates the power in accordance with the position occupied by the measurement within the...
  • Page 10 Neutral zone operating mode [PRO=2] • In this mode, output 1 operates in reverse and output 2 in direct. The set point 1 [ST1], differential 1 [DF1] and neutral zone [DBN] values have to be set. These are parameters for both outputs. The regulator will tend to maintain the measurement controlled within the neutral zone.

  • Page 12 Reverse operating mode with set point and differential switching from digital input. [PRO=8] • In this mode, both outputs operate in reverse, with set point 1/differential 1 or set point 2/differential 2, depending on the status of the digital input. More precisely, with set point 1/differential 1 if the digital input is open and set point 2/differential 2 if closed.
