4.8 Firmware update using replacement of the EPROM
The operator terminal has an EPROM with the firmware of the device. It is required to replace the EPROM with
a new one with the current firmware for any firmware update.
Warning - hazardous electrical voltage!
Danger of electric shock!
The safety instructions and work safety instructions in chapter 1 must be
observed when replacing the EPROM. Power supply to all connectors must be switched off before
connecting or disconnecting them. Circuit boards may only be replaced when power supply is dis­
connected. Mark connectors as necessary BEFORE disconnecting them. Grip circuit boards only at
the edges.
Gefahr des Ausfalls der Alarmmeldungen! AL 300 am CAN-Bus: In order to replace the
EPROM, it is necessary to remove the operator terminal from the system. The removal of the CAN
bus will trigger an error message at the higher level controller (system centre / store computer /
other AL300 Operator Terminals)! Ensure that the service mode has been activated at the AL 300
and/or that the service centre has previously been informed.
Caution: data loss! In some cases, a replacement of the EPROM can result in loss of all settings
in the operator terminal. As a precaution, the settings should therefore be backed up by saving them
using the LDSWin PC software before the replacement. After the EPROM replacement, the settings
saved by LDSWin can be reloaded into the operator terminal.
Risk of damage to the operator terminal! There is the risk of destruction of the EPROM and the
operator terminal when replacing the EPROM due to incorrect handling!
We recommend arranging the replacement of the EPROM by Eckelmann AG or by very well trained
personnel who are very experienced with the handling when opening electronics and the replace­
ment of EPROMs.
ESD-Vorschriften (Electrostatic Discharge) beachten, siehe Kapitel 1.5.
Opening the case of the operator terminal is described in chapter 4.7. The EPROM must be replaced very care­
fully and taking account of electrostatic sensitive devices and components (ESD); see chapter 1.5.
Pay attention to the groove ("polarity") of the old EPROM before removing it as the new EPROM
must also be installed exactly the same to prevent its destruction.
The groove faces the battery or is marked on the EPROM socket.
