SEL751-A Arc Flash Relay

SEL-751A Arc Flash Relay

Does anyone have experience with this relay. More specifically, how are the optical sensors tested during routine maintenance? This looks like a very good relay, but I have concerns about how this unit will be thoroughly tested once it is in service. Thanks in advance for all feedback.
