Pulse Jet Collector Sequential Timers

Client Defined Parameters:

On the upper right-hand corner of the board is a jumper wire with various presents ashore the wire on. This region is marked " Last Output Used". The number on the jumper will be set to rise to the quantity of pneumatic roller valve
. For instance: A 6 position clock load up, for example, the NCC DNC-T2006-A10, joined with a square 25 pack channel that has 5 solenoids and 5 stomach valves would triumph when it's all said and done the last yield utilized jumper set on the number 5 pin.

Just left of focus are the off (stretch) and on (span) potentiometers. The underlying change for texture pack authorities depends on the accompanying standards:

3/4" Valve ) Initial term of 120 milliseconds (.12 on the dial)

1" Valve ) Initial term of 90 milliseconds (.09 on the dial)

1-1/2" Valve ) Initial term of 60 milliseconds (.06 on the dial)

This is the beginning stage and might be expanded until a solid heartbeat terminating sound is discharged from each line. These qualities expect 90 to 100 PSI of clean dry stock air. These qualities are not appropriate to cartridge gatherers.

Off Time

This setting is changed in accordance with clean through the entirety of the sacks in a short time max. The underlying setting for a 25 pack channel can be determined by isolating 180 seconds(3min.) by 5, for a subsequent timespan second.


Contingent upon the clock load upsize, and the fenced-in area it is to be mounted in, some clock loads up should be mounted to a backplate that mounts to the back mass of the electrical nook, while some can be straightforwardly mounted to the walled-in area. IAC nooks are regularly NEMA 4, regardless of whether the application just requires NEMA 12. In the event that the solenoids are to be mounted in a similar nook, they are typically introduced before the clock load up. Know that the solenoid infiltrations and any bulkhead fittings that enter the electrical fenced-in area should convey something similar or preferable rating over the nook all together keep up with the walled-in area rating.


Pressing factor Switch Input

Allude to the IAC distribution "Advantages AND METHODS OF ON DEMAND FILTER CLEANING" for insights about segment determination and utilization for the "pressure switch input". The capacity of this information is to interfere with the cleaning cycle when the info is electrically open.

This info is dispatched with a jumper introduced that makes the load up ceaselessly time when force is applied (L1 terminal) to the load up. This likewise makes the load up begin timing on line #1 each time power is taken out and re-applied.

Eliminating the jumper to introduce an outer pressing factor switch framework, or outside source control like a PLC, will make the load up act in an unexpected way, and necessitates that capacity to L1 stays applied whenever the channel fan is running. At the point when the switch is at first shut, the load up will start to time, and keep on doing as such until the switch is opened. The running board will basically stop the succession until the information is shut again, causing the solenoid valve number after the last one terminated to fire. This implies that if a 16 valve authority began an interesting cleaning on valve 1 (model at 4.5" w.c), and cleaned down to the low (or stop) set point (model 3" w.c.) when it arrived at valve 7, the information would be open at this point. The following time the info shuts, the arrangement would continue beginning with valve 8.

Kindly know that there is an astute wiring technique that will empower the utilization of different clock load up in progression to go about as one bigger load up.

Solenoid Outputs

One lead from every solenoid ought to be wired normal together, and arrived on the solenoid normal terminal. If it's not too much trouble, note that this isn't equivalent to the L2 terminal on the board. Additionally note that the check of this wire need just be estimated to fire each solenoid, in turn, much of the time.

The solenoid yields are numbered 1 through the most extreme number of the board (regularly 3, 6, 10, 20, and 32 position sheets are accessible). The leftover wire on every solenoid ought to be associated with the solenoid valve yield number that decides its terminating request. The number 1 column of sacks doesn't need to be the primary line to fire. A few ways of thinking trust it is smarter to work out from the middle, or in an absolutely irregular example.

Voltage Inputs

Normally in the USA we will utilize 120 VAC sheets, and apply 110-120 Volts AC to the L1 terminal and land the Neutral wire to the L2 terminal. The field electrical technician will ground the fenced-in area that houses the clock.

Our stock sheets are in the DNC family, standard board, 6 to 32 position, 1.5-30 sec. "OFF TIME", and 120 VAC. In spite of the fact that we generally check the voltage prerequisite, 220 VAC is more normal abroad.

Just on the uncommon events, or on little units, like 3 line units, will the off-time be longer than 30 sec?

The number of solenoid yields ought to be more prominent than or equivalent to the quantity of cleaning columns in the gatherer. There will be circumstances where a 12 line authority is being controlled with a 10 position clock. This requires two columns to be doubled up on the board. At the point when this should be done, it is ideal to scatter the multiplying. This isn't an IAC suggested practice.


DNC-T21 series include an all-encompassing cycle (extra clock and change) in the module that can be utilized as a disconnected cleaning improvement.

DNC-T23 series add insight as underlying "On-Demand Cleaning", and Photohelic imitating with its incorporated pressing factor sensor and radiant blue vacuum fluorescent showcase. It very well may be bought with a discretionary 4-20 mA transmitter for distant
