User & Installation manual Appendix
• If the measured A/D value is 60 to 300 add about 50%.
• If the measured A/D value is above 300 add 150.
• Set the calculated value on table
3.3 ALARM DEFINITION “Short Output Level”.
Setting a higher value will result in a less sensitive system; system will
detect short circuits in devices that are near the system but it will not be
sensitive to devices that are further away.
The system will not always be able to detect short circuits in devices that
are far away from the system (dependent on the cable length, resistance,
etc’). Such short circuits generate a lower A/D reading, which might even
be less then a reading of an operative device that is near the system.
To disable the short-circuit control set the value to 999.
Plug & Play
Input/Output cards identification
• After Cold Start, the controller zeroes the cards data that is in the memory and
researches the system.
• After identifying the cards, the controller saves the results.
• Once a minute, the controller runs a check on all the cards and makes sure that
the cards are connected and working properly.
• In case a card is missing or failed, the controller displays a message on the
screen. If the card is found within a minute, the message disappears, if not, the
message turns to an alarm.
• After RESET ALARM the controller turns off the alarm and refers to the missing
card as not existing.
• In order to add a card you must turn off the power, place the card and turn the
power back on. The controller searches for new cards in every power renewal and
adds the new cards to the list.
• The new cards are now considered as cards that must always be found.
• Alarms for cards do not reset automatically. Reset the alarm manually from the
controller or the P.C.
