Units This property input is used to change between English to SI units within the CSM. You must be logged
in as the System Administrator to change this value. When Fahrenheit is selected, the following English
units are used; degrees Fahrenheit pounds per square inch, and gallons per minute (US). When Celsius is
selected, the following SI units are used; degrees Celsius, kiloPascals, and Liters per second. Each time
this variable is changed, the CSM converts all inputs (hard-wired sensors and user-defined variables)
from the old set of units to the newly selected units.
Range = Celsius, Fahrenheit. Default = Fahrenheit
Service Testing
Load Pump 1 (Remote A-Relay 1)
Load Pump 2 (Remote A-Relay 2)
Load Pump 3 (Remote B-Relay 1)
Load Pump 4 (Remote B-Relay 2)
Load Pump 5 (Remote C-Relay 1)
Load Pump 6 (Remote C-Relay 2)
These commandable inputs are used to manually test the chilled water loop pumps. Commanding the
output to Pump Manually On will force the digital output to close so that you may verify pump control
wiring. When a pump output is set manually, it will be indicated on the display by the value@8 (priority
8 indicates Manual or user interface control). The variables must be commanded to “Auto” after manual
service testing is complete so that the CSM application software is allowed to set the output state.
Cooling Tower Outputs 1-16
(Remotes E,F,G,H-Relays 1,2,3,4)
This commandable input can be used to manually test the cooling tower relays. Commanding a certain
output to Manual On will force the relay on a Remote I/O module to close so that you may verify fan
control wiring. When a tower output is set manually, it will be indicated on the display by the value@8
(priority 8 indicates Manual or User Interface control). This variable must be commanded to “Auto after
manual service testing is complete so that the CSM application software is allowed to set the output state.
Load Pump VFD Speed (Remote A,
B, and C-AO 1&2)
Loop Bypass Valve (Remote A-AO 1)
Cooling Tower VFD Speed (Remote
E-AO 2, F-AO 1&2, G-AO 1&2, H-
AO 1&2)
Cooling Tower Bypass Valve
(Remote E-AO 1)
These commandable inputs are used to manually test the associated devices controlled by the CSM’s
analog outputs. Commanding the analog output to a desired percentage will force the analog output to the
corresponding voltage so that you may verify control wiring. When an output is set manually, it will be
indicated on the display by the value@8 (priority 8 indicates Manual or User Interface control). The
variables must be commanded to “Auto” after manual service testing is complete so that the CSM
application software is allowed to set the output value.
