ADJUSTMENT OF THRESHOLDS S1, S2 AND S3 IN MODE ON/OFF REGULATION
9.2.1 REGULATION WITH BAMOPHAR, PRELIMINARIES
Before setting the thresholds or regulation mode, the operating mode must be set.
BAMOPHAR 451 LOG allows 3 operating modes:
1) On/OFF regulation through relays, thresholds S1, S2 and/ or S3
2) Impulse regulation with cycle time, high and low proportional bandwidths, dead zones (S1 and S2)
3) PID regulation with an output signal of 4-20 mA
Thresholds S3, specificities:
S3 may be assigned to an external signal from a sensor (e.g. inductive flow controller) to block the regulation mode (terminals 5 et 6).
In this case the relay S3 becomes N.C. and it opens when the regulation blocking is necessary.
In other words:
- Relay S3 is closed when no voltage applies between terminals 5 & 6
- Relay S3 opens when a voltage applies between terminals 5 & 6 (To block the regulation mode)
Blocking the regulation has the following consequences:
• For impulse regulation mode: relays S1 and S2 keep open (not actuating).
• Inhibition of regulation. – With PID mode, signal 4-20mA will frozen.
• With ON/OFF mode no action occurs on S1 and/ or S2.

METHOD FOR ADJUSTMENT OF PID PARAMETERS
In order to setup values for start-up on PID, we recommend to use the Ziegler-Nichols open loop method.
Proceed as follows:
- Connect a recorder to the analogue output or write the displayed values, then draw the diagram vs. time.
- Set the menu PID on MANUAL mode.
- Reach and keep the measurement close to the set point by adjusting the PID output.
- Reach and keep the measurement close to the set point by adjusting the PID output.
- Apply a step (ΔCde) of 10 % for instance, on the analogue output.
(e.g. If preset value was 30%, apply 40%).
- Note on the diagram the corresponding time for this event (step of +10%).
- Find out on this diagram both times t and T:
t = delay of response and T = Time corresponding to a variation Δm of measurement equal to percentage of variation ΔCde of output
(Δm = ΔCde)
This value may be found out from the slope at the beginning of measurements.
-
Set up the PID parameters with the help of following table:
