11-4-4. Setting of errors (FAIL contact)
Code 53 *Err.4.1-*Err .16 (9 items)
These set how errors are notified to the user. Either of two modes can be set. "Hard
Fail" mode lights the "FAIL" indicator on the LCD panel. When "enable status output
contact" is set for the PH201G distributor (Style B), the FAIL contact remains closed and
the "wash" contact stops operating. If Burnout functions are enabled by Code 32, then
the output becomes Burnout Upscale or Burnout Downscale.
"Soft Fail" mode blinks the "FAIL" indicator on the LCD panel. When "enable status
output contact" is set for the PH201G distributor (Style B), the FAIL contact pulses and
the "wash" contact and maintenance contact continue to operate normally. In "Soft Fail"
mode, notification that "periodic maintenance is due" still functions (service code 55) so
– for this reason – it is better to set "Soft Fail" mode than "Hard Fail" mode.
