Existing Installations Checklist
External circuit components issues
●
120 Vac control power undersized and/or failed
●
Isolation contactors open or damaged
●
Mains power faulty
●
Load disconnected
●
Load failure
●
Line/Load/Control circuits not restored after component
replacement
Verification of recent maintenance functions
●
All disconnected connections restored
●
Isolation devices restored to proper operating positions
●
Proper selection of replacement components
●
Verify suitability of added or modified components to
circuitry
Fault code verification
●
Use of test equipment to confirm/refute validity of fault
code
●
Determine if the fault can be reset
●
Determine if the fault is continuous or intermittent
●
Note operating conditions at time of fault if possible
Common fault codes
●
FC15—Power pole over temperature
●
FC31—Voltage imbalance
●
FC33—Jam
●
FC20—Overload
●
FC35—Temperature sensor
●
FC17—SCR not firing
●
FC18—Shorted SCR
●
FC21—Mains AC voltage loss
●
FC8—Voltage zero cross lost
General Information
120 Vac control power—terminal block connections
●
Run Enable 24 Vdc applied to terminal “Permissive”.
This 120 Vac input must be maintained continuously during
RUN
●
START Command enable from terminal block No
voltage applied to Network terminals. When a 120 Vac
signal is applied to the Network terminal, START control
from the terminal block will not be recognized
●
START Command with 120 Vac applied to terminal
“Permissive”, apply 120 Vac to terminal “Start”. The
signal requirement is momentary, but maintained is
acceptable. Terminals “Permissive” and “Start” may be
tied together for two-wire control START/STOP commands
●
STOP Command Remove 120 Vac from terminal
“Permissive”. Terminals “Permissive” and “Start” may be
tied together for two-wire control START/STOP commands
●
Wire size, minimum—14 AWG (single conductor) to all
terminal block connections. Wire should have no stands
missing or damaged during wire stripping. The use of
terminal ferrules is recommended to maintain connection
integrity
●
Control power supply requirements
– Must meet or exceed steady state and inrush
capacity requirements
– Steady state (sealed) A–D Frames = 85 VA, 120 Vac
– Outrush A–D Frames = 600 VA, 120 Vac for 50 ms
minimum
– Steady state (sealed) E–F Frames = 115 VA, 120 Vac
– Outrush E–F Frames = 1200 VA, 120 Vac for 50 ms
minimum
– Minimum supply voltage 120 Vac measured at the
terminal block
– Maximum allowable voltage drop measured at the
terminal block = 5 Vac
