The "HYD PUMP" light indicates when there is power being applied to the pump motor. If the amber gear up light or the green gear down light is illuminated and the hydraulic pump is energized, the gear doors are open (or in transit).
I still have a couple configuration issues to work out, this is one of them. Yes, the "UNSAFE" light should be extinguished when on the ground. The "UNSAFE" light will illuminate when either of the throttles are retarded with the gear not down, or when there is no power on either the gear up or the gear down panel indicator lights (or gear is in transit).

There are gear down and locked annunciators for nose gear and right gear. Since they are wired in series (nose, right, left) to get to the green down and locked light on the panel, I will be able to see downline as far as the circuit is completed.
Since you are looking at the CGR-30, here is a picture of a CGR-30 install in a friend's C-340.
