Results Obtained
If tachometer generator voltage is erratic or not pre-
sent, refer to the Troubleshooting Guide provided in
the Minster SCRB Eddy Current Coupling Control
Manual.
3. If the power supply and tachometer voltages are
both present, but the meter does not function, return
it to Minster for repair.
NOTE: Field repair of the Minster Bul. 490-0246
Digital Speed Meter is not recommended;
however, a parts list is available from
Minster upon request.
When returning a unit to Minster for repair, make certain
it is carefully packaged to protect it from damage during
shipment. Include, with the unit, a description of the
problem(s) encountered and the serial number of the
press on which it is used. Also include your purchase
order covering the work to be performed and any spe-
cial shipping instructions concerning return of the unit.
REMOTE CONTROLS
If the controls or other off-press control mountings have
been disconnected for ease of shipment, these wires
must be reconnected exactly as shown on the electri-
cal diagram shipped with the press. Terminal connec-
tions and control wires are numbered on the diagram to
simplify wiring.
FLYWHEEL ROTATION
The flywheel is driven by the main drive motor and sup-
plies energy to cycle the slide when the press clutch is
engaged. The flywheel must rotate in the proper
direction!
After the “T” leads are connected to the motor and cou-
pling control leads are connected, if the drive is an eddy
current type perform the steps listed below. Start the
motor and check the direction of flywheel rotation, but
DO NOT CYCLE THE SLIDE.
NOTE: Lube reservoir must be filled, the lube system
must be operational and the air supplied to the
press must be clean, dry, and of sufficient vol-
ume for proper device actuation before the
drive motor can be started.
To Check Flywheel Rotation:
1. Place the POWER, OFF-ON-BAR Selector Switch
in the ON position.
2. Place the Stroking Selector Switch in the OFF posi-
tion.
3. Place the DRIVE MOTOR, FWD-REV Selector
Switch (if supplied) to the FWD (Forward) position.
WARNING
NEVER RUN PRODUCTION WHEN THE MAIN
DRIVE MOTOR IS OPERATING IN THE REVERSE
DIRECTION.
4. Start the main drive motor.
5. With the main drive motor operating, the rotation of
the flywheel (on a flywheel press) or the main gear
(on a geared press) will be clockwise when viewed
from the left-hand side of the press. (See Figure 6C.)
6. If the flywheel (or main gear) rotates in the wrong
direction, stop the main drive motor. Then turn OFF
power to the motor and lock the electrical discon-
nect switch in the OFF position. Correct the motor
and flywheel (or gear) rotation by reversing two of
the “T” lead connections at the drive motor.
CAUTION
DO NOT CYCLE THE SLIDE UNTIL INITIAL LUBRI-
CATION INSTRUCTIONS HAVE BEEN PERFORMED
COMPLETELY.
AIR SUPPLY CONNECTIONS
Air supply to the press must be clean, dry, and of suffi-
cient volume for proper device actuation. Supply pres-
sure must be at least 80 to 125 psi (5.5 to 8.6 Bar). In
addition to proper air supply pressure, it is the cus-
tomer’s responsibility to install an approved air relief
valve — compatible with the pneumatic system — in
the facility’s air supply line if the air pressure exceeds
125 psi (8.6 Bar.)
