SL9600TW Error Codes

Fault Code	Description	Possible Causes	Actions
E1	No decoder found	– Wiring error – Defective decoder – Defective decoder manager	– Check wiring – Move decoder closer to the SL9600TW – Replace
E2	2-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
E3	Open circuit at solenoid	The 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
E4	Short 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
E5	Decoder 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
E6	High Temperature Shut Down	– High temperature – Excessive 2-wire duty cycle at temperature	– Shade controller – Replace SL9600TW
E7	Decoder Programming Failure	– Multiple decoders at one time – Decoder removed before program cycle completes – Failed decoder – Failing SL9600TW	– Retry – Replace decoder – Reple SL9600TW
