WARRANTY

All of National Controls' products are warranted for a period of 1

year against defects and workmanship. Because certain conditions

may apply to different product categories, contact the factory for

detailed warranty information.

IMPORTANT NOTICE TO USERS

NCC products are capable of use in a wide array of devices and

applications. Any device or system incorporating a NCC product

should be designed that, in the event of failure, malfunction, or

normal wear of the product, the device or system will become

inoperative in a manner which will prevent bodily injury or

property damage. In order to keep abreast with the latest

technology, National Controls Corporation reserves the right to

change components, design, and specifications without notice.

1.0 DNC-PS700-A10 OVERVIEW

The Dustronix PS700 is a Digital/Bargraph Differential Pressure

(∆P) Control Meter in the family of Dustronix products, and is

designed to interface with NCC dust collector controls as well as

other controllers. The PS700 is capable of measuring differential

pressure and displaying that value in both analog bargraph and

digital displays. Both Hi/Lo Cleaning and Hi/Lo Alarm set points

can be programmed, each with relay outputs that can be

programmed either normally open, or normally closed. The

Cleaning relay will change state when the measured pressure

exceeds the High Cleaning Set point, and will return to normal

when the measured pressure goes below the Low Cleaning Set

point. The Alarm relay will change state whenever the measured

pressure is equal to or exceeds the window defined by the High

and Low Alarm Set points, and return to normal when the ∆

pressure falls within the window. The PS700 will accept a 0-10"

pressure input. A 4-20mA output loop is provided from the

internal pressure sensor. A 3-digit security code is also provided

to prevent unauthorized changes. The meter is equipped with non-

volatile memory, which will store all operating parameters when

power is removed.

2.0 INSTALLING THE PS700

The PS700 is a front panel NEMA 4 rated control designed to

mount in a 3.625” square panel cutout. Using the brackets

provided (see fig.3, p.11), a NEMA 4 rating is accomplished when

the unit is mounted in a suitable NEMA 4 rated enclosure. Refer

to the Dimensional Drawing and Mounting Information (fig. 3)

for specifics. Remove the electrical terminal block and the

pneumatic fittings in order to mount the unit in the cutout.

DO NOT:

 Install these controllers in harsh environments without suitable

protection. Improper installation will void the warranty.

 Install this unit in an area of high heat or vibration.

 Install this unit close to strong magnetic fields.

3.0 ELECTRICAL HOOKUP

Refer to the corresponding wiring diagram (fig.2) on page 10.

All electrical connections are made to a removable, finger-safe

screw terminal block, which is clearly labeled with terminal

designations. Connect PS700 to a utility power source, which

ranges from 90 to 265 Vac 50/60 Hz. Do not connect this unit to a

"converter" or "inverter" type power source. This unit should be

installed on its own 15-amp circuit. Do not connect this unit to a

power source that is subjected to large switched loads, such as,

electric motors, compressors, electric tools, etc.

WARNING: MAKE SURE THAT THE CIRCUIT THAT YOU

ARE WORKING WITH, IS "TURNED OFF", BEFORE YOU

MAKE THESE CONNECTIONS. SERIOUS INJURY MAY

RESULT IF YOU DO NOT TAKE THE PROPER SAFETY

PRECAUTIONS.

For 120-volt input, connect the "hot" or "high side" of the

incoming power source to "L1" on the terminal strip. Connect the

"return" to "L2" on the terminal strip.

For 240-volt input, connect one side of the 240-volt line to L1 and

connect the other side of the 240-volt line to L2.

Connect the relay outputs, and the 4 – 20 mA current loop (if

used) as desired, and make sure to route any high voltage lines

separate from the low voltage 4 – 20 mA current loop lines.

4.0 OPERATION

The PS700 is shipped from the factory with the default program

(see details below). A pressure input needs to be connected,

outputs wired as required, and power applied to have a

functioning system. From this point, program parameters can be

tailored to the specific application.

5.0 ALARM EVENT

The two instances, which will generate an alarm event on the

PS700 are: the ∆P going below the “Low Alarm Set Point” or the

∆P exceeding the “High Alarm Set Point”. In the event of an

Alarm condition, the Alarm LED will flash Red and the Alarm

Relay contacts will change state. Pressing the "Set/Alarm Cancel"

button will return the relay contacts to its normal state and cause

the Alarm LED to change to solid Yellow to indicate that the

alarm has been acknowledged. Note that an Alarm will

automatically cancel when the alarm condition is no longer

present.

6.0 PROGRAMMING

Refer to PS700 Programming Procedure (fig.1) on page 9. During

normal operation the display will show the pressure differential

being measured. To enter the Programming mode, press and hold

the "Set" button 2 seconds until the digital display shows the

"Low Alarm Set point" as indicated by the Low Alarm LED (red)

flashing. (Note that if a security code has been entered, the display

will show "0.0.0." first. To enter a code, see below.) To change a

value, press the "up arrow" or "down arrow" button. To move to

the next parameter, press the "Set" button. Once in the Program

Mode, all of the items must be sequenced through in order to exit

into normal operation mode. If the system is left in the

Programming mode for more than 30 seconds without making a

change, the unit will change back to the normal operating mode

and not save any changes.

6.1 Alarm Low Set point

To view the "Alarm Low Set point", enter the programming mode

as described above. The Alarm Low LED (red) will flash and the
