PZIT, LICA .etc Definitions

PZIT, LICA .etc Definitions

(OP)
I am quite new to instrument diagrams but have developed a good knowledge of process control so I know what all the various valves and indicators are for, I just have not been able to find out what all the abbreviated labels actually stand for, so i was hoping someone could help.  A list is included below.

LZT
XZV
P/LICA
PZIT
PZV
FQIA
HZS
PIT
PIA
AI
HCV
HIC

RE: PZIT, LICA .etc Definitions

Here's a shot at most of them...

LZT - local zone time
XZV - external zone valve
P/LICA -
PZIT -
PZV - process zone valve
FQIA - fuel quantity indicating alarm
HZS - hydraulic/hydronic zone status/switch/solenoid
PIT - programmable interval timer
PIA - peripheral interface adapter
    - power interface assembly
    - programmable interface adapter
 AI - adapter interface
    - admittance inverter (microwave circuits)
    - airspeed indicator
    - alarm interface
    - analog input
    - application interface
HCV - hydraulic/hydronic control valve
HIC - human interaction componet
    - hybrid integrated circuit

Knowing which field these abbreviations are from would help.
