5.4 (13) Setting of measured value high and low limit switch
Description
1. Set high limit and low limit of switching point when using high limit flow or low limit flow
to set the status output.
Setting range : 0 to
±
105 ft./s of flow velocity
[Relation between status output and set value]
• High limit setting and high limit flow • Low limit setting and low limit flow
2. Setting of hysteresis
Switching hysteresis can be held in the following range.
Set hysteresis within 0 to 20% of the analog output range full scale (with auto 2 range, and
forward and reverse auto range, effective for full scale 1 and 2, whichever small).
Operation (example) Low limit flow velocity: 3.5m/s, high limit flow velocity value: 12m/s,
hysteresis : 5%
