Section III: Press Preparation
1. In order to automatically raise the base roll when the press runs, the HP-3002 temperature control unit needs to be
supplied with a source of power
when the press is in “RUN” mode only
. This source of power is referred to as the
slave
line
. Power for the slave line may be
90-280 volts A/C
. There is no appreciable load on the slave line and #16/2 wire
may be used for this connection. A mini twist-lock connector is included for proper connection to the temperature
control unit.
2. Main system power supplied to the control unit must be rated at
30 amps, 208-240 volts, single phase, A/C
. The supply
circuit must be fused for 30 amp service, and #12/3 wire is recommended for this connection. The control unit must be
properly grounded to reduce the risk of electric shock hazard. A 30 amp twist-lock connector is included for proper
connection to the control unit.
3. Air supplied to the control unit must be
clean, dry, and regulated to 80-100 p.s.i.
Air/line connectors are included for
proper connection to the unit.
4. The base roll assembly supplied with the system should be test-fitted in the intended die station. Position the base roll
assembly in the station and check for interference and proper alignment with the die station drive-gear. Proper fit and
drive gear mesh are critical elements in the system. The base roll should sit level in the station, and the drive gear should
not bottom out into the base roll gear.
