Type IIIC
With type IIIC, two pairs of equivalent inputs (NC (normally closed contact)/NO (normally open
contact) contact pairs for both two-hand buttons) are monitored.
A valid input signal is only generated when the ON state (H/L level) is present at both inputs
within a time of 0.5 seconds (synchronous change, both two-hand buttons actuated) and both
were previously in the OFF state (L/H level).
NOTICE
You can find additional information in the operating instructions for two-hand control.

Switch-off conditions
ATTENTION
Make sure that the switch-off condition is sufficient!
The actuation period for safety mats and bumper must be at least twice as high as the maxi-
mum value for the "test period" of both test outputs used in order to ensure that the switch-
off condition will be detected and that a sequencing error will not occur.
NOTICE
You can find additional information in the operating instructions for the safety mats.
