Implementation
You can implement single-channel or dual-channel configurations. Route the input
wiring for the direction 1 or direction 2 activation terminal and the corresponding
ground, through the safety processing device.
For dual-channel configurations, leave a switching time of 180 ms when switching
between direction 1 (forward) and direction 2 (reverse).
If cross-error exclusion is not allowed, cut off the supply voltage with a dualchannel or two-pole configuration. The supply voltage to the motor starter is cut off
with a single-channel configuration. Therefore, use this type of installation for SIL
3 (category 3, category 4) only if cross-error exclusions are allowed. For example,
use this type of installation when the motor starter and the safety processing
device are installed in the same control panel.

LED Combination and Corresponding Nominal Current
The following symbols indicate whether an LED is on or off.
Use diagnostic functions to find the state of the TeSys H motor starter and
understand the cause of tripping. When there is a detected error or trip condition,
the device is in a safe, disconnected state.
Internal errors cannot be reset and are stored in the device. If more than 14
internal errors are detected, you can no longer operate the device.
Before you can leave the safe, disconnected state, you must reset the trip
condition. To reset an external error, push the SET/RESET button and release it
within 2 s.
The tables in this section describe the combination of LED states, position of
signaling contacts, and reset possibilities, in normal conditions and trip or error
