How to acknowledge and reset indicators, outputs and registers

The [C] button is used for acknowledging and resetting indicators, outputs and
registers as follows:
• To clear the LEDs and the LCD display, press the [C] button. The LEDs and the
LCD are cleared only if the fault situation has disappeared.
• Press the [C] button for at least 5 seconds to unlatch the output contacts. Note that
the LEDs and the LCD display have to be cleared before this (idle mode).
• Press the [C] and [E] buttons simultaneously for at least 5 seconds to clear
recorded data, registers and recorder data and to reset latched relays. The LCD
display being inverted confirms this action.
