Alarms
The Control Parameters for Alarms are identical for both the Master and the Follower
modes of operations. By entering values in the Control Parameters for the Alarms
(CP-12, CP-13, CP-14, CP-15), you can establish circumstances under which the
ML–Trim will alert you to potential operating problems. The Alarm Format (CP-10) can
be set to activate at any combination of low speed, high speed, ramped error or scaled
error conditions. The alarm output can be wired to activate a warning light, a warning
sound, or to shut down the system under specified conditions.
The ML–Trim comes factory pre-loaded with default Control Parameters for Alarms.
These default parameter values are set for widely generic conditions that generally will
not activate the alarm. This allows you to either operate your system unfettered by the
alarm or design your own alarm conditions that are unique to your system. The factory
default Control Parameters for the Alarms are found in Table 3-23. To modify these
default parameters, refer to Table 3-24. If you are uncertain how to enter a Control
Parameter, review the
Operations: Keypad section, page 3-3.
