Operating Manual - ne24.24M Matrix Processor

5.9 Factory Reset Switch

Factory reset is used to clear all user dened preset names and control values and reset them to their original factory

settings. Factory reset to the ne24.24M is accomplished by pressing and holding a recessed switch on the back panel during

power up. The switch is found in a small hole labelled “Reset”. There is a 10 second countdown in the front panel LED display

to indicate a factory reset is about to occur. Releasing the switch or shutting off power at any time during the countdown will

stop the factory reset from occurring. At the end of the countdown, the letters “Fr” ash in the display for about 20 seconds

until factory reset is complete. In addition to resetting all presets to factory default, any password or security settings will be

lost when a factory reset is performed.

5.10 AC Inlet and Power Switch

A detachable AC power cord is used on the ne24.24M. Since the internal universal power supply works from 90 to 240

VAC 50-60Hz, the only change necessary for use with a different AC mains connection is the appropriate AC power cord. The

AC power switch is found on the back of the unit.

6. EXPANSION MODULE INSTALLATION

The Ashly ne24.24M can be ordered from the factory with expansion modules pre-installed to suit the application, or

as a 4 x 4 base unit. Should the need arise to add input or output capacity at a later time, as well as logic output function, ad-

ditional modules can be purchased and easily installed in the eld. There are a total of four expansion slots available, and each

slot accepts either an input, an output, or a logic output module (GPO). The ne24.24M as well as Protea NE Software autodetect

if a slot has been lled, and whether it is an input, output, or logic output. The software interface automatically updates to reect

the current ne24.24M expansion slot conguration. The logic output expansion module can be installed into any slot, however

only one logic output module can be installed. Please note that while eld installation is not complicated, there is a risk of ESD

(electrostatic discharge) damage to circuit board components if the board is improperly handled.

To install an additional expansion module, refer the following procedure to a qualied service technician:

1.) Remove AC power cord from back of unit and place unit on grounded work surface.

2.) Remove the seven top cover screws and remove cover. Remove expansion slot covers from back panel.

3.) Discharge any personal static by touching a grounded object. Carefully remove the new expansion card and at

cable from the ESD protective bag.
