1.6 nEU - Neutral zone, accepted deviation in relation to the ideal
output value.
Possible selections are 0.1...99.9%.
1.7 IE - Internal or external setpoint.
Possible selections are I - internal, or E - external.
Selection of internal or external setpoint. When internal setpoint has
been selected, input B is disabled and the setpoint value is set in menu
1.1. When external setpoint has been selected, the signal type and
range of the setpoint are set in menu 3.0.
1.8 dI - Direct / Inverted controlling method.
Possible selections are dIr - direct, or InU - inverted.
Selection of direct or inverted setting range. When the selection is direct,
a process value > the setpoint will result in an active UP relay. When
the selection is inverted, a process value > the setpoint will result in an
active DOWN relay.
Menu 5.1 = { 2: PI step controller }
1.1 SEt - Setpoint.
Possible selections are 0...99.9% of the input span.
1.2 hP - Proportional band.
Possible selections are 0.01...999%.
1.3 tAU - Exponential average time of the active relay state.
Possible selections are 0.1...999 s.
The period in which the relay is active is exponentially averaged and
forms part of the control loop.
1.4 tP - Minimum pulse time, shortest active time for the relays.
Valid selections are 0.01...10 s.
1.5 nEU - Neutral zone, accepted deviation in relation to the setpoint.
Possible selections are 0.1...99.9% of the input span.
1.6 HSt - Pulse width hysteresis.
Setting should be: 0 < HSt < nEU
Possible selections are 0...99.9%.
1.7 IE - Internal or external setpoint.
Possible selections are I - internal, or E - external.
Selection of internal or external setpoint. When internal has been
selected, input B is disabled and the setpoint value is set in menu 1.1.
When external has been selected, the signal type and range of the
setpoint are set in menu 3.0.
