GLOSSARY OF FEATURES AND FUNCTIONS
Acceleration rate
The acceleration rate is the time required for the controller to increase PWM
output from zero to the maximum allowed. There are four major programmable
acceleration rates for the 1297 controller: the Mode 1 and Mode 2 acceleration
rates (see Section 3A, page 24), which set how quickly the traction motor
accelerates; the pump acceleration rate (see Section 3B, page 47), which sets how
quickly the pump motor accelerates during Lift operation; and the lowering
valve current acceleration rate (see Section 3
B, page 49), which sets how quickly
the lowering valve aperture opens during Lower operation.
In addition, there is a separate acceleration rate for emergency reverse—
see Section 3
A, page 43.
Access rights
Each programmable parameter is assigned an access level (OEM or User) that
defines who is allowed to adjust it. On generic 1297 models, all the program-
mable parameters are assigned OEM access levels; see Table D-1. On OEM-
specified models, the OEM designates the access level for each parameter.
Restricting access rights to the OEM reduces the likelihood of important
performance characteristics being changed by someone unfamiliar with the
vehicle’s operation. In some cases, it may be necessary to restrict a parameter’s
access to ensure that it is not set to a value in violation of EEC or other safety
regulations.
Curtis PMC programmers are available in OEM and User models; the
User programmer can adjust only those parameters with User access rights,
while the OEM programmer can adjust all the parameters. Typically, OEMs
supply User programmers to their dealers and distributors for setting the User-
access parameters (if any) to each customer’s liking, and also for testing and
diagnostics.
Anti-tiedown
The anti-tiedown feature is designed to discourage operators from taping or
otherwise “tying down” the mode switch in order to operate permanently in
Mode 2—see Section 3A, page 44.
BDI
The 1297 controller has a built-in battery discharge indicator (BDI) that
constantly calculates the battery state-of-charge whenever KSI is on—see Section
3C, page 63.
