2. Starts the Elevator Motor, moving the cartridge up for a preset time, then stops the motor.
3. Reports status to the MCS.
Lower Cartridge
----This command:
1. Rotates the rollback mechanism (Rollback Motor) 360 degrees or until the Rollback Home Sensor
activates.
2. Starts the Elevator Motor, moving the cartridge down for a preset time, then stops the motor. (The
Elevator Home Sensor is checked to see if the elevator lowered to the proper position.)
3. Reports status to the MCS.
Stop Elevator
----This command stops the Elevator Motor and reports status to the MCS.
Diagnostics
----The elevator diagnostics move the elevator off the home position (if it is home), return it
home, and then report status to the MCS.

Cartridge Rollback Functions
The MCS software uses the following cartridge rollback commands:
Open Cartridge
----This command:
1. Checks the following before starting the Rollback Motor:
•
The pickup arm is home (Pickup Position Sensor).
•
A cartridge is loaded (Cartridge Present Sensor).
•
The elevator is home (Elevator Position Sensor).
2. Starts the Rollback Motor to roll back (open) the cover for a preset time, then stops the motor.
3. Reports status to the MCS.
Close Cartridge
----This command starts the Rollback Motor to close the cover for a preset time, then
stops the motor.
Stop Rollback
----This command stops the Rollback Motor and reports status to the MCS.
Diagnostics
----The rollback diagnostics move the rollback mechanism off home (if it is home), return it
home, and then report status to the MCS.

Processor Interface Board
The Processor Interface Board controls application of 120 volt ac power to the processor heater. It is part
of a control loop that includes (1) the Processor RTD, which senses the current temperature of the
processor, (2) a Voltage to Frequency Converter, which converts the analog signal from the RTD to a
digital frequency- modulated signal, and (3) the Master CPU, which calculates the power-on duty cycle
required to keep the heater at the required temperature. The primary components of the Processor
Interface Board are 2 relays:
•
Relay K2----When power is applied to theIMAGER and the top hood is closed, this relay is energized
and applies the Line (hot) side of 120 volts ac to the Load 1 terminal of Relay K1. (The neutral line of
120 vac is applied directly to one side of the processor heater.)
•
Solid State Relay K1----This relay is controlled by the PROC SSR DRIVE signal from the MCS Board.
This pulse width modulated signal provides a low (ground) that actuates the solid state relay for duty
cycles controlled by the Master CPU on the MCS Board. When the relay is actuated, 120 vac is
applied to the processor heater via the Load 2 terminal of the relay. LED1 lights when the solid state
relay is energized.
