Back when I was I nAir Defense (just after we’d advancer form coordinated rock throwing) we kept our radars silent to deny info on them from others.
What good is defensive radar if it is turned off?
Condition EMCON. Ooraah!

There is some logic to that. But you need to answer a simple question:
How do you know when to turn them on?
The Vulcan platoon and battery I led had no radars.......or computers.
I am by no means an expert but that would be my first guess. The S-400 are fairly newer systems. Why give away any signals? That would just give information on the better ways to evade them. Not to mention to give away their location so that enemies would know where to target first.
And anyway it’s not like they are going to shoot anyone down. Russia puts them on the ground and it’s a good show and all, but they are not there to defend Syria or ISIS or anyone but Russian forces. They are not going to fire on US jets or Israeli jets for many reasons - including the fact that the US and Israel probably always informs Russia in advance that some or another air attack is coming and for Russia to steer clear. Israel/US doesn’t want to bomb Russians and Russians don’t want to shoot down US allies. So there is no reason to activate them at this point.
Or to avoid taking an anti-radiation missile up the spout!
