FRICK
®
PROTOCOL
DESCRIPTION
All commands for Frick® protocols must be
in ASCII to be recognized (see the Conversion
Chart For Decimal / Hexadecimal / ASCII, lo-
cated later in this manual). The commands can
be in upper or lower case letters. An Evapo-
rator with an ID code of [00] is considered
disabled. ID codes from [01] through [99] are
valid and recognized by the Quantum™.
FRICK® # PROTOCOL SPECIFICATIONS
Frick # protocol consists of commands that
are available for Evaporator control panels.
The Frick # protocol does not utilize a check-
sum. It is better to use Frick Quantum™ ($)
protocol when only communicating to Q4 or
Q5 panels.
The following is a complete list of available Frick® Protocol
# commands:
COMMAND CODE and DESCRIPTION
F1 = Alarms/Shutdowns Annunciation Page 1.
F2 = Alarms/Shutdowns Annunciation Page 2.
F3 = Alarms/Shutdowns Annunciation Page 3.
EW = Read a value from the Table
ER = Change a setpoint in the Table.
Z1 = Current Status (for units 1 – 11)
Z2 = Current Status (for units 12 – 22)
Z3 = Current Status (for units 23 – 30)
All data is returned as integer values. If decimal positions
are assumed, then divide the data by the proper multiple of
10 to get the actual value.
Temperature data, except for Suction Temperature, is re-
turned in the current temperature units as 3 characters with
no decimal position (i.e. 032 would represent 32 degrees
Fahrenheit if the panel temperature units are in Fahren-
heit, or it would represent 32 degrees Celsius, if the panel
temperature units are in Celsius). Suction Temperature is
returned as 4 characters with a + or – as the leading char-
acter (i.e. –010 would represent –10 degree).
Pressure data is usually returned in the current pressure
units. However, the Filter differential reading is always re-
turned in PSIA. When in PSIG or in PSIA, the pressure data
is returned as 3 characters with no decimal position. How-
ever; in order to show the full transducer range, the #IDPS
command returns 4 characters with one decimal position
assumed. The #IDI, and #IDPA commands return 3 charac-
ters that assume one decimal position; therefore, 99.9 is the
highest value that can be returned. When in PSIG, suction
pressure is returned in PSIA. When in Bar and BarA, the
pressure data is returned as 4 characters with two decimal
positions assumed. When in KpaA, the pressure data is re-
turned as 4 characters with no decimal position.
