IntelliVAC Versions
There are two versions of IntelliVAC control. The first type is used tocontrol vacuum contactors that are electrically held, with a single electricalcoil that is economized electronically. The second is used to control mechani-cally latched vacuum contactors. See Chapter 6 for part numbers.
Mounting & Connections
The IntelliVAC control modules are mounted using two (2) screws (seeFigure 1.3). They are typically located in the low voltage control panel of themedium voltage controller (Bulletin 1500/1900 controllers, in the case ofRockwell Automation).
IntelliVAC is interfaced to the Bulletin 1502 vacuum contactors using a“quick” connector, located at the module, a wire harness and “quick” con-nector at the contactor. Control power and other control circuit connectionsare similarly achieved with “quick” connectors.
Configuration
IntelliVAC is easily configured for a wide variety of medium voltage motorand feeder control applications. It is configured using DIP switches, locatedwithin the enclosure (front side). Please refer to Chapter 4 for information.
Bulletin 1500/1900 controllers are shipped with IntelliVAC pre-configured forthe required application. Please refer to the documents provided with theorder.
Firmware
IntelliVAC has firmware stored in flash EEPROM; therefore, this may beupdated in the field (if necessary). The IntelliVAC board firmware isupdated using the mini-DIN connector, which is accessible inside theenclosure.

The IntelliVAC module requires external fuse protection to coordinate withthe power supply and contactor. The fuse ratings shown in Table 3.A allowthe passage of inrush currents expected when the contactor is closed, or fromrecommended external capacitors for the TDUV option. They will alsoprotect the contactor coils in the event of a module malfunction.
The recommended fuses have been tested to ensure realiable protection ofthe module. If the supply voltage is DC, the module must be used with anexternal fuse that is approved for and rated to interrupt the DC voltagesupply. The types listed are Ferraz-Shawmut Midget Fuses (1-1/2" X 13/32").The TRM is a time-delay type, rated 250 VAC. The ATM is a fast-actingtype, rated 500 VDC.
Table 3.A IntelliVAC Fuse Protection
The IntelliVAC module must be connected to a common ground terminal(PE) on the controller panel. The ground terminal is located on top of themodule enclosure (refer to Figure 3.5)
ATTENTION: It is important that IntelliVAC isproperly grounded using the ground connection provided .Failure to do so may result in damageto equipment or personal injury.

The IntelliVAC can be applied with two- or three-wire control circuits. Thecontrol system utilized will determine the configuration of the input wiring.Consider the following input and output for the type of control used:
• Terminals 9&10 Close Contactor• Terminals 15&16 Contactor Status
In either case, the CLOSE input must receive a maintained voltage high tokeep the contactor closed.
Note:1. When used with electrically held contactors, the IntelliVAC allows closecommands every six seconds. This is to ensure the rated contactor duty cycleis not exceeded.2. If a contactor close command is applied and then removed in less than 500milliseconds the IntelliVAC may fault and the module status LED will turnred. To clear the fault, module power has to be removed and reapplied.3. If IntelliVAC powers up configured for an electrically held contactor, andthe vacuum contactor is detected as being closed, the module will not respondto a close command until the auxiliary contact input is in the correct (open)state (see Chapter 5).

Two Wire Control
If using two-wire control, the CLOSE contactor input is maintained high usinga single contact. Momentarily opening this input will cause the IntelliVAC toopen the contactor. Maintaining the contact will provide a CLOSE commandto IntelliVAC (given that all permissives are satisfied). If a fault occurs, inaddition to cycling control power to the IntelliVAC module, the CLOSEcommand must be removed for a minimum of 25 milliseconds, before beingre-applied. Refer to Figure 3.6.

When used with electrically held contactors, the IntelliVAC allows closecommands every six seconds. This is to ensure the rated contactor duty cycleof 600 operations per hour is not exceeded. For motor jogging operations, thesecond control input, or OPEN command, will close the contactor for as longas the input is present, and open the contactor when the input is removed.(Refer to Figure 3.9). This method will bypass the standard six second motorre-start delay for jogging purposes only.

The IntelliVAC can be configured to provide time delay under voltage(TDUV) protection. The feature is available to keep electrically held contac-tors closed during a voltage dip or brief power loss. This option may requirethe addition of a capacitor (see below). Refer to Chapter 6 for typicalcapacitor sizing. The capacitor is connected to terminals 1(-) and 2(+) of theIntelliVAC. (Refer to Figure 3.10).
Table 4.B of the “Setup and Commissioning” chapter has the dip switchsettings to provide TDUV from 0.2 to 2 seconds. For 120VAC controlpower, a 0.2 second delay can be provided without an external capacitor.For 240VAC control power, delays of up to 1 second can be providedwithout an external capacitor. An external capacitor is required for longerdelays.
If the undervoltage condition persists beyond the set delay time, the contac-tor will be opened and an undervoltage fault condition will occur.

Monitoring & Troubleshooting
The IntelliVAC module has two light emitting diodes (LEDs) and relayoutputs to indicate the status of the contactor and the module.The LEDs arevisible on the front of the module and the relay outputs are accessed on thebottom front of the module.
Figure 5.1 IntelliVAC LEDs
The Module Status is indicated with a Green LED if the module is functioningproperly and has a valid configuration. If the module powers up with aninvalid configuration the LED will be Red, indicating a Fault condition whichwill not allow the contactor to close. If the module powers up properly andexperiences an undervoltage condition when attempting to close the contactoror while the contactor is closed, the LED will be Red (Fault). If the contac-tor does not close properly, a Fault is generated, the LED turns Red, andinputs are inhibited until the module power is removed and reapplied. If theprocessor has an internal fault, the LED will be Red, the outputs will becleared, and the processor will be reset. If the reset is successful, the LEDwill be Green and the module will respond to the control inputs. The inputcommand must be toggled before the module will respond to a new command(rising edge triggered).
Module Status output relay has a normally open contact. The contact is openduring a Fault condition (LED red), and closed during a healthy condition(LED green).

Table 5.A IntelliVAC Status Indication
The Contactor Status is indicated with a yellow LED that is off until aCLOSE command is received. The LED will stay on if the contactor closesproperly, until the contactor is opened.
Contactor Status output relay has a normally open contact. The contact isopen when the contactor is open (LED off), and closed when the contactorhas received a close command or if it is closed (LED on).
Notes: u Applies only to power-up conditionv Fault is reset by cycling control powerw If a contactor close command is applied and then removed in less than 500 milliseconds the IntelliVAC may fault and the module status LED will turn red. To clear the fault, module power has to be removed and reapplied.x For mechanical latch contactors a close command does not need to be maintained for the contactor to remain closed (resulting in a yellow state for contactor status).

Table 5.B Module Troubleshooting
Problem or Trip indicated Indication of the following conditions Possible solutions
Contactor does not energize • Motor Protection activated. • Investigate and reset.
• Both Status LEDs off • Check Control Power
• Loose connections in control circuit
• Verify IntelliVAC power input plug is in place and properly seated.
• Verify internal control fuse has not opened. (Refer to Fig. 4.1 for location)
• Module Status LED 'Red' upon power up. • IntelliVAC faulted. Cycle control power to reset.
• Improper setting of dip switches. Check settings and cycle control power.
• Loose connection in control circuit.• Verify contactor auxiliary set up. Reference Publication 1502-5.0 (400A) or 1502-5.1 (800A) - Auxiliary Contact Set-Up Procedure.
• Verify circuit continuity (is contactor plug connected properly).
Contactor closes momentarily and will not reclose. • Module status LED red contactor status LED off. • Coil damaged or connections are loose. Repair and cycle control power.
• Auxiliary Contact Assembly improperly adjusted. Reference Publication 1502-5.0 (400A) or 1502-5.1 (800A) - Auxiliary Contact Set-Up Procedure.Cycle control power to reset.
• Armature Plate obstructed from closing to coil face. Verify no foreign material behind the armature plate. Cycle control power to reset.
• Undervoltage fault(no TDUV), control voltage dipped below trip point. Cycle control power to reset. Verify voltage levels are 100 to 240VAC, 100 to 250VDC.
• Both status LEDs OFF • Check internal control fuse. Verify IntelliVAC operation in test mode, before applying Medium Voltage. (Refer to Fig. 4.1 for location).
Contactor opens during operation. • Motor Protection activated. • Investigate and reset.
• Stop command initiated. • Verify circuit.
• Module Status LED 'Red' • Undervoltage fault(no TDUV), control voltage dipped below trip point. Cycle control power to reset. Verify voltage levels are 100 to 240VAC, 100 to 250VDC.
• With external capacitor and TDUV feature activated, undervoltage condition for longer than programmed TDUV time. Undervoltage fault activated. Cycle control power to reset.
• Contactor Status feedback between Terminals 11 & 12 on the IntelliVAC has closed. The IntelliVAC will de-energize the holding coil, thinking the contactor has opened for other reasons.
• Both status LEDs off • Check control voltage and internal control fuse. (Refer to Fig. 4.1 for location).
