Troubleshooting
Chapter 6 provides information to guide the user in troubleshooting
the 1336 PLUS. Included is a listing and description of the various
drive faults (with possible solutions, when applicable) and alarms.
Fault Display
The LCD display is used to indicate a fault by showing a brief text
statement relating to the fault (see figure below). The fault will be
displayed until “Clear Faults” is initiated or drive power is cycled. A
Series A (version 3.0) or Series B HIM will display a fault when it
occurs, no matter what state the display is in. In addition, a listing of
past faults can be displayed by selecting “Fault queue” from the
Control Status menu (see Chapter 3 for more information). Refer to
Table 6.A for a listing and description of the various faults. Table 6.B
provides a listing of faults by number.
Clearing a Fault
When a fault occurs, the cause must be corrected before the fault can
be cleared. After corrective action has been taken, simply cycling
drive power will clear the fault. Issuing a valid Stop command from
the HIM or Control Interface option (TB3) will also clear a fault if
the [Flt Clear Mode] parameter is set to “Enabled.” In addition, a
“Clear Faults” command can be issued anytime from a serial device
(if connected).
Contact Description
Refer to Figure 2.3 for a schematic representation of contacts
CR1-CR4. Contacts in Figure 2.3 are shown in an unpowered state.
When powered, the contacts will change state. For Example: During
normal operating conditions (no faults present, drive running), the
CR3 Fault contacts at TB2-13 & 14 are open, and the contacts at
TB2-14 & 15 are closed. When a fault occurs, the state of these
contacts will change.
