About Series 497 Hardware Limit Detectors

For FlexTest IIm systems, a limit detector on each Series 497 Conditioner continuously compares its associated
transducer output value to preset upper and lower limit values set in the Hardware Limits tab.

When a conditioner’s upper or lower limit is exceeded, its limit detector is tripped, triggering an interlock.

Note:

Hardware limit detectors are supported as an option that must be enabled.
