2.2 HYS / SPH - Setting of relay 2 hysteresis
Possible selections are 0...99.9%.
The hysteresis is set in % of the input signal. The hysteresis is the
difference between the setpoint and reset values.When the selected
function in menu 4.1 = {004 = Setpoint window}, the upper window value
SPH is set in this menu. When the selected function in menu 4.1 = {005
= Hold}, menu 2.2 has no function.
2.3 InC / dEC - Setting of active relay 2 for increasing / decreasing
input signal
Possible selections are InC or dEC.
If InC is selected, relay 2 will be activated when the input value is high er
than the setpoint and deactivated again when the input value is lower
than the setpoint minus the hysteresis. If dEC is selected, relay 2 will be
activated when the input value is lower than the setpoint and deactivated
when the input value is higher than the setpoint plus the hysteresis.
When the selected function in menu 4.1 = {004 = Setpoint window},
InC will result in the activation of the relay, and dEC will result in the
deactivation of the relay inside the window. When the selected function
in menu 4.1 = {003 = Pre-setpoint or 004 = Hold}, menu 2.3 has no
function.
2.4 dEL - Setting of relay 2 time delay
Possible selections are 0...99.9 s.
The time delay is the period in which the input value must be present
before the relay switches state.
2.5 HyS - Setting of hysteresis for setpoint window
Possible selections are 0...99.9%.
When the selected function in menu 4.1 = {004 = Setpoint window},
menu 2.5 is active. The hysteresis is set in % of the input signal and is
placed outside the window.
A hysteresis less than 1% is typically an acceptable value.
