H03 Td (Sec); H04 +Opt Clamp & H05 -Opt Clamp; H06 Sv Choice - Zener MSC-3 Instruction Manual

MSC-3 Start Up

H03 Td (sec)

Range: 0.0...5.0 sec/r
• Press  to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press  to accept the new value OR
• Press ESC to abandon the value change.
The H03 Td (sec) value determines the estimated component added to the PID output
A low H03 Td (sec) contributes a small corrective component and appears to dampen the systems
response. If too low, it affects may be unnoticeable.
A high H03 Td (sec) value may improve the response to a step input, but may also destabilise the
system.
H04 +Opt clamp & H05 –Opt clamp
Range: -100.0...100.0 %
• Press  to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press  to accept the new value OR
• Press ESC to abandon the value change.
The H04 +Opt clamp and H05 -Opt clamp values determine the upper and lower limit thresholds for PID
output saturation. The PID output will never exceed these values. When the PID output is being clamped
the integrator anti-windup activates to prevent the integrator from accumulating error continuously.

H06 SV choice

Available Choices:
• Press  once to begin a selection.
• Use the ▲ / ▼ buttons to select the set point reference.
• Press  to confirm the choice.
The H06 SV choice is the reference value the PID controller regulates the process variable to. Invalid
reference choices will not appear in the reference list.
