PCS-PFC Quick Set-up Instructions
The information presented is in Bimba’s best engineering opinion and should be used for reference only. Recommendations derived should be verified under actual operating
conditions. Bimba reserves the right to change specifications without prior notice.
Set the Span adjustment or end position
1.
Set control voltage to maximum (10 VDC).
2.
Turn SPAN CCW until rod is in the desired fully extended position.
3.
The green LED should not be on continuously.
Decel adjustment
The decel adjustment regulates the distance over which the PFC rod slows to a stop.
Low Decel settings provide fastest speeds. High Decel settings provide the most
stability for high loads. If deadband is set too low for the load, the rod will overshoot
and undershoot the target position, oscillating before settling to a stop.
1.
Locate TP1, TP3, and Decel adjustment.
2.
The DECEL setting can be varied from 0.5 to 13.5 VDC.
3.
Adjust DECEL trim pot to 3 V between TP1 and TP3 ini-tially.
4.
Turn DECEL adjust and monitor voltage with DMM.
General Procedure
1.
Set-up the PCS control under load, installed in the machine. If it is not under load it will need to be readjusted.
2.
Under load, vary the control voltage from 0 to 10 V. Movement should be smooth between end posi-tions with minimal chatter.
3.
If there is chatter, adjust decel and deadband for optimal performance.
4.
Leaks in air hoses and fittings or cracked fittings will cause erratic operation.
5.
Air pressure may cause erratic operation. Pressures from 60-80 psi should yield good results.
