SW1 Test Mode The control is placed in the Test Mode by holding the pushbuttonswitchit h SW1 forf 2 - 5 seconds.d In the Test Mode most of the control timings will be shortened by afactor of sixteen (16), with exception of fault recognition times. The GREEN LED will flash: 1 second on / 1 second off. When entering the Test Mode, the RED LED will flash the last lockoutfailure code one time. Test Mode will automatically time out after 30 minutes.
