10.7 The sequential timer board or the digital reverse pulse controller requires 115 volts (60 cycles) input power. Power consumption is less than 50 Watts.
10.8 The valves operate on 115 volts (60 cycles). The power required is 22 watts. The terminal block on the sequential timer board or digital reverse pulse controller is labeled for the input power and the valve outputs.
NOTE: The digital reverse jet pulse controller with “Pulse on Shut down” feature must be wired with a continuous 115 volt supply. The control must not be wired in parallel with the fan motor starter. (Exception is when using an Amtech combination motor starter with disconnect as this has a dedicated 115V transformer.) 10.9 The digital reverse pulse controller, that monitors filter differential pressure, requires pneumatic hoses to be connected. Beside the filter access door are 2 ports which should be connected to the digital reverse pulse controller (if so equipped). These ports are labeled “HIGH” and “LOW”. At the base of the digital reverse pulse control enclosure are 2 port s also labeled “HIGH” and “LOW”. Interconnect the ports between the collector and pulse control with air tight tubing.
11.0 SMOKE DETECTION/FIRE SUPPRESSION (OPTIONAL)
NOTE: All smoke detection/fire suppression installations must be performed by a qualified technician and in accordance with local, state, and national codes/regulations/laws (if any).
11.1 Smoke detection and fire suppression is an important aspect of the installation procedure. Fires are a common occurrence in dust collection systems and the comprehensive collection system should be designed for when a fire occurs, not if. Various systems are available for smoke detection and an even greater list of fire suppression technologies exist. Fire sprinkler systems for collectors MUST be properly connected. In most cases, this is the closest building’s fire sprinkler system. ALL smoke detection/fire suppression systems should be periodically inspected and maintained.
12.0 PRE-START UP
12.1 If not already verified in the electrical section, check rotation of fan by tur ning “ON” for a brief instant (JOG) and verifying rotation. Ro tation must be clockwise when viewed “OVER THE MOTOR” from the discharge side. If the rotation is correct, start the motor.
12.2 Check that rotary air locks, screw conveyors or any other directional dependent components are rotating the correct direction.
12.3 Check the compressed air system for leaks. Confirm 90 PSI minimum air pressure and 100 PSI maximum air pressure.
12.4 Ensure that no air leaks exist in the seams of any field assembled cabinet components such as hoppers, plenums, filter cabinets, drum lid kits, drums, etc.
Warning: Compressed air pressure higher than 100 PSI can damage the filters and the dust collector’s structural integrity.
12.5 Check that the compression couplings of the pulse valves are tight.
12.6 Energize the sequential timer. The suggested “ on time ” is 0.10 seconds and “ off time ” is 30 seconds. The digital reverse pulse control has been preset at the factory. However, it is recommended to verify that each valve will pulse, by manually activating the valves through the pulse control.
