MAGNEHELIC GAGE CONTROL WITH

SUPRA-CLEAN TIMERBOARD

When using a Magnehelic Gage with Supra-Clean

pulse timerboard, the timerboard is always set to

“Continuous Clean” pulse mode. If the filters are

operating at a higher or lower differential pressure than

desired, adjusting the pulse frequency (Pulse Delay)

can often modify the steady-state pressure differential.

The factory setting is 10-second intervals. Adjust the

“Pulse Delay” on the Supra-Clean timerboard and

monitor the pressure drop on the Magnehelic Gage. A

longer interval will raise the operating differential

pressure and a shorter interval will lower the operating

differential pressure. Allow sufficient time for the system

to stabilize after each adjustment before further

adjustment is made. Adjust unit the desired pressure

differential is reached.

PHOTOHELIC GAGE CONTROL WITH

SUPRA-CLEAN TIMERBOARD

When using a Photohelic Gage with Supra-Clean pulse

timerboard, the timerboard can set to “PS” pulse mode

(pulse cleaning activated by the Photohelic control) or

“Continuous Clean” pulse mode to override the

Photohelic Gage. With the Photohelic Gage control, the

desired pressure differential can be maintained by

adjusting the high and low setpoints on the gauge.

Adjust the upper setpoint to the desired differential

pressure setting plus 0.25" (factory recommended

setting is 3"). Adjust the lower setpoint to the desired

setting minus 0.25" (factory recommended setting is

2.5"). This allows a 0.5" “deadband” and the pulse

system will maintain the desired differential pressure

(factory recommended operating point is 2.75"). If the

differential pressure remains above the desired

operating point, the pulse frequency can be increased

(shorter “Pulse Delay”) as previously described. The

high and low needle setpoints on the Photohelic Gage

can be adjusted as the filters season and continuous

pulsing occurs. Adjust both needles upward in 0.5"

increments until pulsing stops. Continue adjustments,

when required, until the high setpoint reaches 6". No

further adjustments should be made above 6" w.g.

SUPRA-VIEW PULSE PANEL

When using the Supra-View panel, the pulsing controls

can be set to “PS” pulse mode (“On-Demand” cleaning

similar to Photohelic control) or “Continuous Clean”

pulse cleaning. The Supra-View comes standard with a

cartridge differential measurement/display, pulse time

sequence controls and a “Customer usable” high

cartridge pressure alarm contact all in one enclosed

assembly. The high, low and alarm setpoints are

adjusted by opening the enclosure door and adjusting

the appropriate selector switches for desired control.

Adjustments to the setpoints can only be done with the

door open. Refer to the Supra-View

Installation and

Operation Manual

for adjustment details, or look on the

inside of the Supra-View enclosure door for operating

instructions.

SUPRA-I.Q. DIAGNOSTIC PANEL

The Supra-I.Q. Diagnostics Panel can be set to operate

in Continuous Clean, Setpoint Clean (similar to

Photohelic control), or “Autotune” Clean mode. Autotune

mode is designed to conserve compressed air usage

while maintaining lowest possible cartridge differential

pressure. It allows the minimal amount of compressed

air usage while maximizing filter life. In Autotune mode,

the controller will automatically adjust the filter

differential pressure to obtain the most cost-effective

setting. Please refer to the Supra-I.Q.

Installation and

Operation Manual

for a complete listing of operating

parameters and adjustment instructions.

ALL CONTROL OPTIONS

As filter cartridges become loaded with dust, the

differential pressure across the filters will increase. This

will result in a loss of air volume. Should the dust

collection capture effectiveness be reduced, open the

flow control damper to return the system to the original

design air volume.

6. SERVICE

BEFORE SERVICING,

NOTE THE FOLLOWING:

1. Disconnect electrical power to the unit and

control panel.

2. Shut off and slowly bleed compressed air supply

from the manifold.

3. Collected dust may be hazardous. Consult proper

authorities for handling and disposal.

4. Collected dust may be a potential fire hazard.

Welding, grinding or operations involving open

flames should NOT be performed without fire

protection measures in place. Refer to Section

1 of this manual for additional precautions.

5. Wear appropriate protective clothing when servicing

the dust collector.

6. Disposal of collected dust must be according to state

and local environmental regulations.
