3.9.10 RELAY AND DIGITAL OUTPUT CONTROL
This command allows the user to directly control the operation of the relay or digital output. This function may be used to
control a remote application (turning off/on equipment). Keep in mind that the control of the relay is also shared by the
monitor and alarm function. If you wish to solely use the relay as a remote control you must disable the monitor and the alarm
functions from operating the relay.
COMMAND CODE:
09
COMMAND SYNTAX:
09 [Key Code] [Relay/Digital] [ON/OFF] #
WHERE:
Key Code = Reference current key code
Relay = Zero (0)
Digital = Non Zero (1-9)
ON/OFF = Zero (0) or Non Zero
EXAMPLE: 09 11 0 1 # = Energize (turn on) the relay
09 11 1 0 # = Turn off the digital output
3.9.11 READ ANALOG INPUT VALUE
This command is used to directly read the current analog input voltage at the analog to digital converter, prior to any
integrating or scaling of the voltage.
COMMAND CODE:
62
SYNTAX:
62 [Input] #
WHERE:
Input = 1 through 8
EXAMPLE:
62 1 # = Read analog input channel number 1
62 4 # = Read analog input channel number 4
3.9.12 READ ANALOG INTEGRATE VALUE
This command is used to read the current analog voltage after the integrator. (The integrator is a math routine which
averages the last predetermined number of readings from the analog to digital converter.
COMMAND CODE:
63
SYNTAX:
63 [Input] #
WHERE:
Input = 1 through 8.
EXAMPLE:
63 1 # = Read analog integrate value input channel number 1.
63 2 # = Read analog integrate value input channel number 2.
3.9.13 READ ANALOG HIGH (MAXIMUM) VALUE
This command reads the maximum analog voltage which occurred since the last time it was reset. The maximum voltage
will also include the time and date at which it occurred. This feature monitors all analog inputs at all times. When you are
ready to start recording the maximum voltage you will need to reset this feature using programming command code 66.
COMMAND CODE:
64
SYNTAX:
64 [Input] #
WHERE:
Input = 1 through 8
EXAMPLE:
64 1 # = Read analog high value, input channel number 1
64 3 # = Read analog high value, input channel number 3
