4.1.21 RPM FREEZE
The RPM Freeze input (when grounded) allows the operator to request that PTO maintain the
current engine speed. Locking on to a fixed engine speed is desirable in applications where the
input is subjected to electrical noise which in turn causes the engine speed to fluctuate. The
RPM Freeze Switch is normally open.
Installation
This input is wired to pin 4/18 on the CPC.
Programming Requirements & Flexibility
The options for this digital input are listed in Table 4-19.
