CARB Approved IOM 12 - ARID Permeator AT-150 -VR-201-Z /VR-202-Z Installation of the AT-150 Control Panel PERMEATOR comes complete with a separate electrical control panel. This panel must be located in a zone free area and includes an hour meter to register cumulative running time of the unit and a pressure indicator/controller. The panel also contains a main power On/Off switch, and a power supply for the pressure, vacuum and oil level sensors. Also, a galvanic isolation barrier is used to ensure that no ignition sources can be passed from the control panel to the main PERMEATOR skid, located in the hazardous area. The vacuum pump is equipped with a 2.0 HP motor that operates on 208V/3-phase/60 Hz power. The steady-state load is estimated as follows for this motor: Watts = (1.73)x V x Ix PF, where 1.73 =square root of 3, V=volts,I=amps, and PF=power factor. Assuming power of 1.5 KW, PF = 0.8, I= 5.2 amps. Operating expenses are calculated as follows: 1.5 kW x 7.2 hours/day(@30% duty cycle) = 10.8 kWh/day 10.8 kWh/day x $0.10/kwh= $1.08/day @ 30% duty cycle $1.08/day x 30 days/mo. = $32.40/month The system requires a 20 Amp service rating on the circuit breaker and connecting wiring used at the site. Motor wiring is typically 12 or 14 gauge, depending on run length, local codes and electrician recommendation. The 24 v do signal cables should be 18 gauge, depending on run length, local codes and electrician recommendations. The detailed installation manual found in the electrical control box provides a wiring diagram and instructions for qualified electricians to connect the power supply to the electrical panel. The manual also provides further instructions for completing the control loop and power output wiring from the panel to the junction box housed within the PERMEATOR cabinet. The panel should be located in a Zone Free, non-hazardous area located indoors. This area should also be easily accessible to technicians and site operating personnel. The panel is pre-wired at the factory and field tasks include only the connection of 3-phase power from the site and sensor and control inputs from components housed within the Main cabinet and previously connected to the junction box located within the Main cabinet. Installation of Communications for AT-150 Control Panel to the Veeder-Root In-Station Diagnostic (ISD) System Integration of the ARID PERMEATOR Control panel to the Veeder-Root TLS/ISD panel requires linking two connections: one for any alarm and the other connection for On/Off actuation of the PERMEATOR. The On/Off actuation is linked to a normally open(N/O) contact on the motor starter; when the starter coil is pulled in, the contact becomes closed and the change of state is registered by the Veeder-Root TLS/ISD panel. It may be necessary for the Certified Permeator Technician(CPT) to consult with a certified Veeder-Root technician to ensure proper communication between the PERMEATOR and the ISD system. 11
