5.4.5 Fault Mode

The Fault Mode Display provides information to the operator when a
fault occurs and allows the operator to review fault history. Refer to
Section 7 for details. Fault codes are displayed by 3 alpha characters.
The first and second characters (reading left to right) are the initials for
the applicable English-language fault name. The third or right-most
character can be either A, c, or d to denote when the fault occurred. "A"
denotes Acceleration. "c" denotes Constant speed. "d" denotes Decel or
Stop.
Press the UP Arrow key
Press [RESET] key
This Fault History can only be accessed during a fault condition. While
the active fault number is being displayed, use the Up and Down Arrow
keys to scroll through the Fault History. An additional Fault History
complete with Time and Date stamps is also available for viewing at any
time in F085 through F093.
 5.4.5.a
Once a fault condition has been corrected, pressing the Reset key
will return the readout to the Status Display mode. To reset faults,
press the [RESET] key on the keypad. Alternatively, most faults will
reset upon removal and return of control power. Overload trips will
NOT be reset in this way unless sufficient time has passed for the
Thermal Register to regain sufficient capacity for a successful
3 1
restart (see section 3.1).
NO. C A1 A2
 5.4.5.b
Because most trips can be reset by removing control power, remote
reset can be accomplished this way. A N.C. remote contact (or
push-button) can be placed in the control power supply to A1 or A2
and opened to facilitate a trip reset. See figure 5.4.5.b for a
suggested connection.
