ZM6 close to saturated

Vicky and Rahul pointed out that ZM6 looks more saturated than usual. The alignment changed last Tuesday and the LL VOLTMON (H1:SUS-ZM6_M1_VOLTMON_LL_OUTMON) has been saturated since then, plot attched. The DACs themselves (H1:FEC-43_DAC_OUTPUT_6_{8,9,1,0,11}) are not saturated hence we haven't we had verbal alarms. Unsure of the difference between VOLTMON and DAC output channels, comparism plot attached.

ZM6 is used in the SQZ ASC so we want to make sure we have range on this optic and might think about trying to offload to ZM4 or ZM5.
