Profile Pressure Alarm Setpoint

Word

Description

OSC57

Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
Clamp Open Slow Profile. The module sets alarm status bit SYS06-B12 when clamp pressure equals or exceeds this entry during
the Clamp Open Slow Profile. A zero entry inhibits SYS06-B12.
