Invalid input data will be ignored and the computer screen will direct you to enter data in a valid range. The program starts with the Panasonic Title screen, as shown below (Software versions may be different): The operator is prompted to enter the proper password and operator name.
MAIN SCREEN The Main Screen is the screen which controls normal operation of the Irradiator Automatic Irradiator. After the operator has entered the operator password, entered their name, and pressed the OK key, the Main screen appears on the monitor, as shown below: 1) The operator uses the mouse to select the Unattenuated(High) or Attenuated(Low) dose.
After changes in exposure dosages and exposuere time, “Save” button saves the corrent configuration into the parameter file and “Cancel” button restores the original settings. When setting the exposure dose or time for each tray, there is a menu option which also allows the user to set individual exposure dose or exposure time value for each slot in the selected tray.
View\Status Log screen shows a series of events. It shows date, time, and event description. It can be printed or saved as another file from the menu. It is also useful for emailing/showing to a Panasonic Service Engineer. View\Reports MENU...

Single Step Adv button - This function advances a magazine by single step(s) into the Irradiator. The number of steps from home appears in the step counter window to the right of this function. Single Step Rev button - This function reverses by single step(s) a magazine out of the Irradiator. The number of steps from home appears in the step counter window to the left of this function.

Single Step Down - Single steps the badge push-up mechanism down. . The number of steps to the home position is displayed in the step counter window to the left of this function. Overrun button - This function causes the badge push-up mechanism to travel to the number code read position or to the irradiate position.

Unload Tray button - This function unloads tray into the changer. Stop button - This function stops current badge processing. Exit button - This function returns the operator back to the Main screen for normal system operation. MODE\READER CHECK\CHANGER TEST MENU The Magazine Changer will automatically load up to ten (10) magazine trays holding 50 badges each or 500 badges into the Irradiator.

MODE\READER CHECK MENU -- CHANGER TEST MENU Up/Down control - A toggle function which turns ON/OFF the shelf feeding drive (vertical drive) motor. In/Out control - A toggle function which turns ON/OFF the magazine drive (horizontal drive) motor. Magaginze Motor In button - Advances a magazine into the Irradiator Irradiator.

Parameters MENU -- SYSTEM PARAMETERS MENU This menu allows critical system operational parameters or data to be modified by an authorized manager. This menu is password protected by the highest (manager) level password. IMPORTANT NOTE: The Dose Rate functions, Set Unattenuated (High) Rate and Set Attenuated (Low) Rate are the calibrated dose rates of the CS-137 source for the high and low attenuation settings.
Page 22
Traveling dose is given by the dose rate multiplied by the element travel time in front of the beam. Knowing the timing for one step is 0.002s, one way traveling time is: 18.3 x 0.002s = 0.0366s Total time for round trip is: 0.0366s x 2 = 0.0732s Example: If the dose LOW is 0.0281mSv/s and dose HIGH is 0.281mR/s, LOW traveling dose is:...

This requires the TLD Reader to be calibrated relative to the PSDL or SSDL and the Irradiator exposure adjusted to this using the same reference TLDs. Please discuss with Panasonic in detail. For Reference - Automatic Internal Calculation of Source Decay: = ( Initial Dose Rate ) e - ( 0.693 t / T )
Parameters MENU – Individual Dose Setting MENU This menu allows individual dose setting parameters for the selected tray to be modified by an operator. “Use Tray\Individual” toggle function is used to select tray dose exposure setting or individual dose exposure setting for each badge in the selected tray.
Parameters MENU – RS232 Options MENU This menu allows RS232 option parameters to be modified by an operator for serial communication or printing through RS232. RS232 Communication ON If this option is selected, the IRRADIATOR will transmit data string using selected comm. port, baud rate, data bit, stop bit, parity, flow control and interface mode.

blocking the path of the badge or failure of the badge sensor. This error may be corrected by following the troubleshooting suggestions given in B-Type Error General Trouble shooting section. M0 Errors An M0 error occurs as the magazine is advancing to the next slot if the timing sensor does not detect a signal within the specified time limit, even though the specified number of pulses were transferred to the pulse motor.
