]
• If the test input is connected to plus, the transmission function is deactivated. The sensor can thus be tested
for correct functioning. If the input is open or connected to minus, the transmission function is activated.
NOTE!
• The ESPE is self-testing. No external test is required.
• Max. valid test duration: < 150 ms
•
A test duration of ≥ 150 ms results in a warning
(see section “12.3.2 Emitter” on page 65)
• A test duration of > 10 s results in an error
(see section “12.4.2 Emitter” on page 68)
Synchronization
• The emitter and the receiver are synchronized by means of optical synchronization beams.
These are the upper and lowermost beams.
