RPM ThetaController Installation

Use orange safety (traffic control) cones to setup barriers. Practice established safety protocols. 

Open all doors needed to access components.

Use a magnet to disable tamper switches for all open doors. Use adhesive tape to disable older mechanical switches. 

Verify sensors mounted in control pillar door are receivers

To disconnect sensor cable, turn collar counterclockwise and pull away from sensor.

Move LD-260 switch to OFF position. The PWR ON LED will turn off.

For vehicle monitors (VM-250), the converter is located behind the LD-260

For train monitors (TM-850), the converter is usually located in the electronics cabinet on the control pillar

Use medium Phillips (PH2) screwdriver. Retain screws.

Retain part for reinstallation

Needle nose pliers may be used

For a VM-250, use Pliers. Retain hardware.
For a TM-850, remove mounting screws. Use medium Phillips (PH2) screwdriver. Retain screws.

Use a tag or tape. Include date of removal, description of failure symptoms, country, site, and lane number. Retain or dispose of component per Nuclear Smuggling Detection and Deterrence (NSDD) guidance or contractual requirements.

Use small slotted screwdriver. Remove wires from I1 terminal and I2 terminal.

These wires go to Terminal Block 1 (TB1). Use small slotted screwdriver

Use small slotted screwdriver. Remove green wire from Q1 terminal.

Use slotted screwdriver to pull down tab and rotate Nano Controller up. Use medium Phillips (PH2) screwdriver if Nano Controller is mounted with screws.

Use a tag or tape. Include date of removal, description of failure symptoms, country, site, and lane number. Retain or dispose of component per NSDD guidance or contractual requirements.

The tab on the back of the ThetaController must be in the DOWN position to install on the mounting rail.

On bottom of ThetaController, push tab up to lock into place.

Remove wire from (+) terminal on RS232 to RS485 converter power/signal connector (usually orange color). The other end of this wire connects to terminal block 3 (TB3) at position 9. Use small slotted screwdriver to tighten wiring connections.

Remove wire from (-) terminal on RS232 to RS485 converter power/signal connector (usually yellow color). The other end of this wire connects to TB3, position 10. Use small slotted screwdriver to tighten wiring connections

Use wire from I1 terminal on Nano Controller (usually black color). This wire comes from the black infrared occupancy sensor.

Use wire from I2 terminal on Nano Controller (usually black color). This wire comes from the yellow infrared occupancy sensor.

Use wire from Q1 terminal on Nano Controller (usually green color). The other end of this wire connects to TB2, position 6.

Use wire from 12 VDC IN (+) terminal on the Nano Controller (usually red color). The other end of this wire connects to TB2 between positions 16 and 20, which are all +12 VDC.

Use wire from 12 VDC IN (-) terminal on the Nano Controller (usually red color). The other end of this wire connects to TB2 between positions 10 and 15, which are all grounded.

Move LD-260 switch to ON position. The LED PWR ON will illuminate.

The SC-770 controller will display "OK" following Power On Self-Test (POST) and background measurement. 

To reconnect sensor cable, align connectors, push towards sensor, and turn the collar clockwise.

Stand to side of control pillar. Open door with infrared sensors.

IR1 and IR2 will be illuminated

Press button to display speed information for latest occupancy on ThetaController.

Contact CAS operator to verify “SP” appears in RAVEN [Radiation Alarm and Video Event Notification] data stream and/or the daily file. Speed messages can also be viewed by connecting a computer to the SC-770 Ethernet output.

Remove all magnets and/or adhesive tape from door switches.
