* The 4-0 mA input is passive. It requires an external 1-4 V isolated power
supply. Default settings are 0 to 100% (0=4mA and 100=0 mA). Zero and
full scale can be modified via the second Point Setup screen. Values can be
between -99 and 999. Applications of 4-0 mA can be for pressure tranducers,
temp, flow, humidity, level, etc.
To set the units of measurement, repeatedly press '↵' to cycle through the fields
until the Units field is highlighted.
Enter the units required using the '
list and the' ' or ' ' key to move the cursor left or right respectively.
Note: This is a text field only and does not effect the operation of the system. It
will not be available if DNO, DNC, ENO or ENC is selected.
You can use the ' ' and ' ' keys together to delete the character before the
cursor and '
box will move onto the next field.
Select the point to be used for defrost as previously described. Use the '
' ' keys to alter the point type code, if necessary, to "Dno" (defrost interlock,
normally-open relay) or "Dnc" (defrost interlock, normally-closed relay).
Select the point to be interlocked to the defrost and repeatedly press '↵' to
cycle through the fields until the Def Int Pt field is highlighted. Use the '
' keys to alter the point number to the defrost input.
For example, if probe 1 is a temperature probe and point 16 is a defrost input
contact, set 16 as the defrost interlock in probe 1's settings.
Select the point as previously described. Repeatedly press '↵' to cycle through
the fields until the High field is highlighted. Set this field to set the value
at or above which an alarm will occur by using the '
through the character list and the ' ' or ' ' key to move the cursor left or right
respectively. When the high temperature alarm point has been set, press '↵' .
The edit box will move onto the next field.
Repeat the operation for the Low field, to set the value at or below which an
alarm will occur. Press '↵' to move the edit box onto the next field. Repeat the
operation for the Delay field. Set the length of time (in minutes) that the fault
must be present before an alarm is raised.
Select the point as previously described, then repeatedly press '↵' to cycle
through the fields until the Action field is highlighted. The status display shows
the alarm action number. Use the '
actions. These alarm actions can then be set to carry out the desired functions.
For example, point number 3 could be set to have alarm action 1 which sets the
siren and dials out to a modem. Whereas, point number 4 could be set to alarm
action  which sets the siren, dials out to a pager as well as the modem, etc.
The alarm actions are as follows:
