- On, when K1 and K2 are energized
- Permanent on, when relay K1 and K2 are energized
- Flashes with 1 Hz when the unit waits for the start
signal after fault free operation (power up of the unit)
- Flashes fast with approx. 3 Hz when the start button
is pressed and all conditions for an override are
fulfilled during muting
- Flashes fast with approx. 3 Hz when at stepping
operation the unit waits for interruption of the
light curtain
- Flashes with failure code to indicate normal indication
states that disable the energisation of the output
relays (e.g. after not allowed interruption of the
light curtain) until the start button is pressed
- Flashes with failure code to indicate
special failures (e.g. undervoltage)
Off, when unit is on special failure mode
- Normally off when relays K1 and K2 are energized
- Continuously on, when unit in muting mode
- Shows the same failure codes as LED
run 1 (except on special failures)
