TE: The PLC is equipped with a lithium battery to keep the program stored while the power is
shut down. The battery will need to be replaced every 3 to 5 years, depending on usage. A visual
warning will be displayed on the interface when the battery drains to a certain level. Battaries can be
purchased through your Hyd-Mech Distibutor.
The programmable length control (PLC) uses signals from limit switches, control panel switches, an
encoder (rotary shaft or linear) and information which is programmed into it, to supply accurate
automatic length control and sawing functions.
The inputs used include;
- a head up limit switch, a head down limit switch;
- the machine function switches & push-button
- also a signal from the auto/manual push button (telling the PLC whether
auto or manual operation has been chosen).
An encoder is attached to the shuttle assembly and travels with the shuttle to provide length
information to the PLC. A proximity switch and target, mounted to the gearbox drive pulley or behind idler
wheel, provides blade speed input to the PLC.
The programmed information includes logic put into the PLC be its manufacturer, as well as
information programmed in, through the keypad, by the assembly plant. Information from the assembly
plant is referred to as the parameters. The parameters are important for the PLC to provide accurate
sawing lengths and blade speed display. Following is a description of each parameter and the procedure
to access them.
To view the PLC parameters:
For semiautomatic "P" models, refer to the PLC key description of on Pg.2.7.
For automatic models;
In manual mode, with front vise switch in 'CLOSE' position press FWD. and REV buttons
simultaneously ( not more than 0.5 sec. apart). The PLC will prompt for a password which is obtainable
from Hyd-Mech Saws. If the password is correct a screen of parameters will appear. The display will
show two lines of parameters at a time. The first display is for the machine's self calibration of it's length
control. If the length control calibration is necessary, follow the calibration procedure on page 3.20. To
move through the parameters use the cursor keys to scroll up or down. To change a parameter, cursor to
that parameter line, and, using the number keys, type in the new value and press enter. To leave the
parameters press the Auto/Man key. The following page lists the available parameters and their defini-
tion.
