Valve Pulse

Rate at which the valve dispenses shot. The Valve Pulse

is factory set to match the best ow characteristics of

the media (cast steel or cut wire). The typical operation

rate is 8 Hertz.

Test Connector

Provides access to

diagnostic voltages.

• 0 - 10 Vdc input

• 24 Vdc “Enable” input

• 6 - 20 Hertz pulse rate

• 0 Vdc common

Operation

Remote Valve Driver

Valve Driver Panel (behind the cover plate)

*Diagnostic LEDs

Valve On. Indicates when power is being sent to the MagnaValve’s electromagnet. When the

LED is on, the valve is on for full capacity ow rate. When the LED is o, the MagnaValve’s

permanent magnet has stopped the media ow. When the LED is blinking, the shot ow is

being regulated.

Vin > 0.25 Vdc. Indicates that an analog signal input greater than 0.25 Vdc has been received.

When this LED is o, no media ow is allowed. The input signal range is 0 -10 Vdc. At 10 Vdc,

the MagnaValve will open to full capacity. The relationship between the 0 -10 Vdc input signal

and actual ow rate is non-linear.

24 Vdc Enable. Indicates that the 24 Vdc Enable Signal has been received. When the LED is

o, the MagnaValve is inhibited and no shot will ow. This feature is provided as an on-o

action so the 0-10 Vdc input signal does not have to be disabled or removed.

24 Vdc Power. Indicates that 24 Vdc is available to operate the electromagnet for media ow.

It should always be available and able to supply 2 Amps.

All four LEDs must be on in order to have media ow.

Diagnostic LEDs*

The large knurled screw on the front cover of the Remote Valve Driver can be removed to gain

access to the factory adjustments. Please refer all adjustments to qualied personnel.
