Chapter 7 2 Overview
The PRINTER's HELP modes can be broadly classified into the following types:
♦ Modes for ROM version display / version upgrade
To display the version of the main PCB ROM, the panel PCB ROM, relay PCB ROM, Tape
Dispenser ROM (option).
♦ Modes for adjustment / specification setting
These modes set the functioning of variable resistors and switches by using the battery PCB
unit's EEPROM to memorize settings made on the operation panel.
The ADF is an option. All of these adjustments and settings are required at the time of installation.
2 Overview
WARNING
Failure to heed the above could
result in crushed or otherwise
injured hands or fingers.
IMPORTANT
♦ Modes for sensor and switch displays
These modes provide displays of the conditions of sensors and switches.
● New adjustments and appropriate settings must be made after the battery PCB unit is
replaced and after initialization setting has been implemented (using HELP-027).
♦ Modes for function checks
These modes permit the running of function checks on:
individual motors, given series of operations, and electrical circuits.
When these modes are used to check motor functioning, the motor being checked is run by itself,
but interlocks are suspended. When such checks are run, take care not to put hands or fingers
in
motor-related moving parts that could start up unexpectedly.
