Troubleshooting Guide for ASTAT-CD Plus Solid-State Starters
Symptom or Error & (Error Code) Possible Cause Measures to be taken
Display OFF No control voltage Check wire harness and control voltage
Main breaker tripped or fuse blown
F1 fuse blown on power supply PCB Check and change
Bad connection of flat ribbon wire Verify connectors
joining power supply PCB to control PCB Check power supply board and logic board for 5VDC.
Use a DC voltmeter on the power supply board, (-) lead
of voltmeter on the top lead of C6 (located next to the
black heatsink on the right edge of the power supply
board) and the (+) lead of voltmeter on top lead of
Diode AD21 or R25 (located on the upper right corner
of the power supply board)
Fans not running No voltage to fans Verify voltage and connections
Equipment does not respond to F2 fuse blown on power supply PCB Check and change
STOP / START controls
Motor will not start but display No power to gate circuits Check 12VDC on Power Supply Board. Use a DC
shows – Ramp, Full, etc. voltmeter on the Power Supply Board, (-) lead of
voltmeter on the top lead of C6 (located next to the
black heatsink in the right edge of the Power Supply
Board) and the (+) lead of voltmeter on bottom lead of
Diode AD20 (located near the lower left corner of the
black heatsink on the Power Supply Board).
Frequency error (Ex10) No 1L1 phase or Check 1L1 phase and/or
(admits 45Hz
≤
f main
≤
65Hz) frequency is out of range mains frequency
Overload trip (Ex11) Excessive load or excessive current Verify overload conditions during starting time and
during starting steady state. Check settings in parameters "Nxxx",
"Lxxx", and "oxxx"
Synchronism loss (Ex13) Phase 1L1 lost Check 1L1 phase
Phase A, B, C thyristor (Ex14) Short circuited thyristor Check thyristor module
(Ex15) Check ground connections and voltage to ground
(Ex16) Poor ribbon cable connection
No output phases Check 2T1, 4T2 and 6T3 phases
Heatsink thermostat (Ex17) Heatsink thermostat tripped by Check for adequate ventilation
overheating or defective Check thermostat and wiring
Motor thermistor (Ex18) Motor thermistor tripped by Check thermistor and wiring, if no thermistor terminal
overheating or defective 5 and 6 must be jumpered
