Parameter
HGT CLB “ENTER” This is to be used only if calibration is required. Call Hyd·Mech Service department for instruction.
ACT HT Actual Height Value.
Value that must be entered after performing Head Height Calibration procedure.
This value represents the head full stroke height. (This parameter is not present on machines
which have a head up and down limit switch. S-20A, H-2A and some early M-6/20A)
FVO DEL Delay time for the opening of the fixed VISE.
A value of 00 is approximately equal to about one second. (I.e. 75=.750 seconds delay)
CLS TIME Delay time for closing front or shuttle VISE. (I.e. 75 =.750)
SPD FCTR Blade speed adjustment number.
If Actual Blade speed is different than displayed Blade Speed, a new speed factor will need to
be calculated. (Providing wheel Trgs is set correctly): Actual speed / Display = adjustment factor
Adjustment factor X Existing speed factor = New speed factor.
WHEEL TRG Number of targets per revolution of the idler wheel. S-20A, S-23A, H-2, M-6/20 = , H-6/20,
H-26/32 = 6
BRKN PROX Allows user to override signal from prox switch in case it is broken (When set to value - 0; ma-
chine will not run with broken proximity sender. Set to value - ; allows machine to Run).
PROBLEM #
No Display
POSSIBLE CAUSES;
. No power to the PLC.
2. PLC unit failure.
3. Faulty connection of cable between PLC & Interface
DIAGNOSIS:
. Check POWER LED (see PLC Inputs and Outputs in this section - Status lights) - to be on when the PLC is
switched on.
• If the light is on, PLC may have failed. Check for proper connection of cable at PLC & at interface. If con-
nection is secure replace. If light is not on - check the (2 amp) PLC fuse.
• If the fuse is OK, check power to it.
PROBLEM # 2
No Blade Speed Display.
POSSIBLE CAUSES:
. Fault at proximity sensor
• Bad sensor, misadjusted sensor (gap should be approx. 0.05”)
• Contamination on the end of the sensor
2. Fault at the PLC
• Bad connection of sensor wiring
• Faulty PLC input
