12 Memory and System Layout
The heart of the ATD 50 Actuator
®
is a Motorola 68HC11 microprocessor. The
microprocessor accesses an EPROM and EEPROM for specific software
instructions and parameters. The general software instructions are stored in the
EPROM. The application and door specific parameters are stored in the EEPROM.
EPROM
The universal operating software with general functions and instructions is stored in
the EPROM. These instructions, alone, are not enough to correctly operate the
ATD 50 Actuator
®
.
EEPROM
The application parameters and instructions are stored in the EEPROM. The
EEPROM contains all parameters which are entered or modified using the SERsoft
programming software. The more specific instructions for the ATD 50 Actuator
®
are
stored in the EEPROM. The parameters and instructions stored in the EEPROM
can be saved in a SERsoft programming software file. Contact MPC for more
information.
MICROPROCESSOR
T
he microprocessor follows the general (operational) instructions of the EPROM
while accessing the EEPROM for application specific parameters.
After a system-wide initialization all parameters and instructions in the EEPROM
are deleted. Only the operating software in the EPROM remains. Therefore, the
ATD 50 Actuator
®
will not operate
A system-wide initialization is started by any one of the following:
1) Removing the EEPROM; or
2) Selecting the menu "Software Reset" or
3) Selecting the menu "Factory Settings" in the SERsoft programming software.
NEVER SPECIFY ÒRETURN TO FACTORY SETTINGSÓ UNLESS THE
PARAMETERS HAVE BEEN SAVED IN A SERsoft FILE!
