7.6.3 Control Box 65-3290-00 Operation
Basic Magna-Ram Pneumatic control box with automatic crossover option.
The Control Box main functions are:
1. Stops / Raises / Lowers the Elevator.
a. In stop position both up and down air is blocked- no movement.
b. In the Down position the Ram Lower pressure regulator setting is used to adjust the down
force. The Up air is exhausted.
c. In the Up position the Ram Up pressure regulator setting is used to adjust the up force. The
Down air is exhausted.
i. The Raise Pushbutton must be depressed to allow the Ram to go up.
This is a safety precaution.
2. Power Vents Selector. Opens a valve to allow atmospheric pressure to the underside of the
follower plate. This condition allows the removal of the follower plate from the drum.
a. Close (auto): Only allows the vent to be opened if the Ram is in the Raise position and the
Ram Raise pushbutton is depressed. Once the pushbutton is released the vent will close.
i. A timer (bottom of panel) is used to delay the opening of the vent valves so that
there is a positive ram upwards movement before the vent is opened.
ii. The timer is reset when the Raise pushbutton is released.
b. Open (manual): Open the vent if the Ram is in the Raise position.
i. This is used as a maintenance position.
ii. The vents will close when the Ram is in the Hold or Lower position.
3. Pumps On Pushbutton: Turns off depressurization valves and sends air to both Pump #1 & 2 pilot
regulators.
a. Sends a signal to turn off depressurization valves on single and dual Magna-Rams.
b. Both pumps of existing ram turn on and operate at pump air regulation setting.
4. Depressurize Pushbutton: Turns off both pumps of the existing panel and opens the
depressurization valve.
a. Single system: Opens the depressurization valve allowing existing material to flow under
the follower plate.
b. Dual system: The depressurization valve will open on the existing panel, if the Pumps are
Off on the corresponding controller.
i. On dual systems the depressurization valve will not open if the opposing Pumps are
on. Prevents material from backfilling drum of existing system.
5. Pumps Off: Turns both Pumps#1&2 off on the existing panel.
6. Pump #1 Regulator: Adjust the Pilot Pressure / Pump Pressure of the Pump #1.
a. A 1:1 ratio pilot regulator is used so that the pilot and outlet pressure are the same.
7. Pump #2 Regulator: Adjust the Pilot Pressure / Pump Pressure of the Pump #2.
a. A 1:1 ratio pilot regulator is used so that the pilot and outlet pressure are the same.
8. Pump#1 Pilot Pressure: Pilot pressure being sent to the Pump#1 pilot valve.
9. Pump#2 Pilot Pressure: Pilot pressure being sent to the Pump#2 pilot valve.
10. Pumps On Green Indicator: Turns Green when the Pumps are turned on.
11. Drum Empty Switch: When the Empty drum Limit Valve is energized Indicator turns Red.
a. The existing pumps#1&2 will turn off.
b. Dual System – A start signal is sent to turn ON the opposing system pumps.
