MAIN POWER DISCONNECT SWITCH
A main power disconnect switch may have been supplied in this control package shipment as a separate component or included in a custom or special
control box. This switch is designed to disconnect the primary voltage to the press and lock it out. Please refer to the enclosed wiring schematics for
proper wiring of this switch.
OSHA 1910.217 (b)(8) and ANSI B11.1 require that:
1. A main power disconnect switch capable of being locked in the off position shall be provided with every power press control system.
2. If the machine already has a main power disconnect switch, it must be checked for the “locking off” feature. Some switches use construction
which can be easily altered mechanically to comply with this requirement. If this is not possible, or an electrical disconnect switch is not provided,
then you must obtain and install a proper disconnect switch. (For a proper disconnect switch, please contact Rockford Systems.)
MOTOR STARTER
A reversing or nonreversing motor starter may have been supplied with this control package as a separate component or included in a custom or
special control box. The main purpose of this starter is to start and stop the main motor and to drop out the main motor when a power failure occurs.
Please refer to the enclosed wiring schematics for proper wiring of this starter. If an existing starter is used, a 120-V AC coil and NO auxiliary (main
motor forward) contact are required.
OSHA 1910.217 (b)(8) and ANSI B11.1 require that:
1. The motor start button shall be protected against accidental operation.
2. All mechanical power press controls shall incorporate a type of drive motor starter that disconnects the drive motor from the power source in
the event of control voltage or power source failure. It shall also require operation of the motor start button to restart the motor when voltage
conditions are restored to normal.
These requirements are normally met by using a magnetic motor starter. This starter should operate with a 120-V AC coil which is powered from
the secondary of the control transformer on the control panel. Refer to the electrical schematics supplied to obtain details of how to wire the starter
and associated motor START/STOP push buttons.
For proper tie-in of the furnished clutch/brake controls, the starter requires an auxiliary normally open contact. (For a proper starter, please contact
Rockford Systems.)
CUSTOM OR SPECIAL CONTROL BOX
In place of the standard control box previously described, you may have ordered and received a custom or special control box. This box usually
includes a magnetic motor starter and disconnect switch complying to the previously described requirements. Be sure to wire in primary voltage
and components to terminals as indicated on the enclosed wiring schematics. 120-V electrical power to clutch/brake controls, operator controls,
solenoids, etc., must be obtained from a transformer with isolated secondary.
