ADVANCED POWERLIGHT FEATURES.

Voltage Smart PhotoMaster PM400, PM400R, PM800 & PM800R

Automatic Discharge

Each time the AC line power is disconnected or switched off, the unit will automatically flash-dump most of the stored power, and then discharge by resistor the remainder of the stored power. This removes all of the flash capacitor charge to prolong the life of the unit and is a much safer condition for storage, for transporting, and replacement of flash tube or modeling lamp. Even if the flash tube is defective or absent, the internal resistor will discharge all power within 30 seconds after the unit is turned off. This is a feature, over which the user has no control.

Unit Number Assignment

This feature allows the user to assign a UNIT NUMBER (1 to 9) to each PhotoMaster in the studio. The UNIT NUMBER is necessary when INFRARED remote control is used with the PM400R or PM800R models (see accessories.)

To assign a UNIT NUMBER, the startup sequence will need to be interrupted. Turn PhotoMaster AC power OFF. With the unit OFF press and hold the ½ stop “UP” button then turn the power switch to ON, continue holding the ½ stop button until the display reads “ir” then release the button. The Digital display should read “ir” when you press and release the ½ UP button again, and the display will then read “Un - 1”, or some number 1 to 9. To change the UNIT number, press and release the 1/10 UP/DOWN arrow buttons until the desired number is displayed. To save and close the assignment feature and save the UNIT number, press and release the 1/2 UP arrow button again. This allows the startup sequence to finish and save the new settings. Each “R” unit’s default unit number is set at “Un - 1”. You must re- set the unit number with the 1/10 adjustment buttons, or the default “Un 1” will automatically be assigned.

Wireless Setup.

The “R” units are pre-set for Infrared wireless operations at the factory and no adjustments are necessary for operation. See next section.
