Alarm Button (Remote Display)

What does A-17 mean?

This alarm is displayed on the remote terminal when a button has been held down for an extended period (more than 10 seconds), or if the keypad is disconnected. It suggests a physical issue with the terminal's buttons, or a faulty connection of the keypad itself, which can prevent proper input.

• A button on the remote display keypad is physically stuck in the pressed position due to debris, damage, or wear.
• A foreign object (e.g., dust, grit) lodged under a keypad button, causing a continuous contact closure.
• Damage to the keypad membrane or internal circuit board, leading to a permanent 'button pressed' signal.
• The remote display unit was disconnected from the drive while a button was being held down.
• Internal fault within the remote display's input sensing circuit, misinterpreting an open button as pressed.
