| A control panel may optionally be used with PASS. The control panel may have a ESTOP switch (i.e. mushroom emergency stop switch), as well as a manual reset button, which may be embodied as a keyswitch or push button. When a control panel is used with PASS, a Manual Reset is required in order to activate PASS, and thus, start projector operation. In most cases, this is a simple keyswitch action but could also be a simple momentary push button. And when a Control Panel is used, PASS continually monitors the ESTOP button. If the ESTOP is pressed, PASS will immediately terminate all color and intensity signals, and forcibly close the shutter. PASS will also open the projector interlock signal path (ILDA pins 4 and 17). | A control panel may optionally be used with PASS.

| PASS may be controlled by, and may illuminate LEDs on an external control panel that is connected to PASS. Below is a description of the control panel connections. When PASS is not connected to an external control panel, then PASS will automatically reset into a “ready” state shortly after power up. When PASS is connected to an external control panel, then PASS will not power up in a “ready” state and instead, will wait for the “Manual Reset” from the control panel. | PASS may be controlled by, and may illuminate LEDs on an external control panel that is connected to PASS.

| - | PASS monitors the power supplies that feed the scanner amplifiers. This voltage can be between +/-20 volts and +/- 30 volts. The manor in which you connect PASS to the power supply and to the scanner amplifiers depends heavily upon whether you are using two separate single-axis scanner amplifiers, or one dual-axis scanner amplifier. | + | PASS monitors the power supplies that feed the scanner amplifiers.
