Part 1: Controller initialization upon initial control power energization (assuming capacitors fully discharged)
Control
voltage applied.
Microcontroller performs internal self-test.
Validation of configuration values.
Check of actuator position.
Charging capacitors.
1
Check of capacitor voltage.
Check of capacitor integrity,
energy storage capability.
Cyclic self-test, ready for operation-see
Part 2.
Part 2: Cyclic self-test (each millisecond)
No
command input.
Check internal power system.
Check communications port for input.
Within 300 s from loss of control power,
an OPEN operation can be initiated using
pushbutton. During this time,
microcontroller operation is maintained
using stored energy from the capacitors.
Check of actuator position.
Test capacitor capacity (every 7 days).
Check of capacitor voltage.
Check of actuator position.
Check of capacitor voltage.
Cyclic self-test is initiated every 150 ms
(energy saving mode).
Internal level 24 V present.
Internal level 24 V not present.
Footnote:
1. If the capacitors have been fully
discharged for a very long time,
charging time may be significantly
longer than indicated. If capacitor
charging time is much longer than
expected on initial energization, refer
to “Capacitor charging after very long
de-energization” on page 40 of the
“Maintenance” section of this
instruction manual.
Check of coil circuit.
Status signalization via LED (Green LED
indicates ready, red LED indicates error).
