5.2 ANALOG OUTPUT MODULE PROGRAMMING CODE DESCRIPTIONS

Channel Selection - “On/Off” “3231”

: This code allows the user to select (switch on or

off) the number of channels that are to be utilized. This is determined by the number of

analog output signals desired. To achieve this, input the code “3231”, then depress the

“3” button to turn a channel “On” or depress the “1” button to turn a channel “OFF”.

Depress the “2” push-button to scroll to the next channel. Any channel that has been

disabled (switched off) will remain at the current output it last received from the control-

ler. Powering the unit down then back up will set all the outputs to default to 4.0 mA.

I.D. Code “3232”

: This code allows the user to enter the ID code assigned to each re-

mote analog output module. Only one ID code is assigned by the factory for each mod-

ule covering 8-channels. This means the same code should be entered in the first eight

channels. If a second eight channels is installed, a different code must be entered in the

second set of eight channels.

Low Range “1321” / High Range “1322”

: This code allows the user to scale the chan-

nels as desired. For example, if you wish to monitor a CO sensor from 0 to 200 ppm,

enter “0” for the low range and “200” for the high range. The output will be 4.0 mA for “0”

and 20.0 mA for “200”. If the value goes beyond 200, the output will be limited to 20.0

mA and will not show a value beyond 200.

Another example will be if a variable speed fan motor is to be driven with one of the

outputs. You may want to set the low range to “25” and the high range to “100”. Then

the output will begin to rise from 4.0 mA starting at 25 ppm and continue to a maximum

of 20.0 mA at 100 ppm.

To achieve this, input code “1321” for the low range or code “1322” for the high range

and use the “3” button to increment the value or the “1” button to decrement the value.

Depress the “2” push-button to scroll to the next channel.

Activate on Sensor or Zone “2333”:

This code allows the user to control the outputs from

a single sensor or a group of sensors (zone). If “zone” has been selected, the output

from the 4-20 mA output channel will be from the sensor in that zone with the highest

value reading. Zone numbers placed into this section must match any zone numbers

assigned in the sensor input table.

To achieve this, input code “2333” and use the “1” or “3” button to select the desired

activation. Use the “2” button to scroll to the next channel.

Monitor Sensor “3113” or Zone “3112”:

This code allows the user to select the sensor or

zone number to be monitored. If “zone” has been selected in the previous menu func-

tion, the user will not be able to access code “3113” as it will have been locked out. If

“sensor” has been selected in the previous menu function, the user will not be able to

access code “3112” as it will have been locked out.

To achieve this, input the code “3113” or “3112”, then depress the “3” button or the “1”

button to increment or decrement the value. Depress the “2” push-button to scroll to the

next channel.
