Dust Monitor 102 in PSL
Dust Monitor 102 has stopped responding in the last couple of hours and needs to be power cycled/re-started.

Failed dust monitors which need power cycling are usually accompanied with an invalid status on their HOLDTIMEMON PV (STAT = TIMEOUT). With this in mind, I've extended the code to mark channels which have zero std-dev counts with a preceding asterix if their holdmontime pv is also invalid. Example for PSL-102 which is currently bad:
H1:PEM-CS_DUST_PSL101 OK
*H1:PEM-CS_DUST_PSL102 WARNING: dust counts did not change, please investigate
H1:PEM-EX_DUST_VEA1 OK
