SL9600TW Error Codes

Print
Fault CodeDescriptionPossible CausesActions
E1No decoder found– Wiring error
– Defective decoder
– Defective decoder manager
– Check wiring
– Move decoder closer to the SL9600TW
– Replace
E22-wire over current– Shorted wiring
– Wire connected to dirt
– Improper connections
– Failed decoder (shorted)
– Valve connected directly to 2-wire
Troubleshoot wiring problems by undoing the last thing you did when it worked before, and/or by breaking the 2-wire system in half to isolate the
problem, then in half again as needed
E3Open circuit at solenoidThe decoder detects no solenoid current when activated:
– Open solenoid
– Poor connections/wiring between decoder and solenoid
– Broken decoder
– Check decoder to solenoid connections
– OHM solenoid
– Replace solenoid
– Replace decoder
E4Short circuit at solenoid – Poor quality wiring between SL9600TW and decoder (length, connections, high resistance, 2-wire connected to dirt)
– Failing decoder
– Failing SL9600TW gives errors on “all” decoders, multiple decoders with same address
– Test 2-wire quality (end-to-end resistance, resistances to earth ground)
– Isolate decoder in error (test close to decoder manager)
– Check for duplicate addresses
E5Decoder communication error – Poor quality wiring between SL9600TW and decoder (length, connections, high resistance, 2-wire connected to dirt)
– Failing decoder
– Failing SL9600TW gives errors on “all” decoders, multiple decoders with same address
– Test 2-wire quality (end-to-end resistance, resistances to earth ground)
– Isolate decoder in error (test close to decoder manager)
– Check for duplicate addresses
E6High Temperature
Shut Down
– High temperature
– Excessive 2-wire duty cycle at temperature
– Shade controller
– Replace SL9600TW
E7Decoder
Programming
Failure
– Multiple decoders at one time
– Decoder removed before program cycle completes
– Failed decoder
– Failing SL9600TW
– Retry
– Replace decoder
– Reple SL9600TW
