FIGURE 25. POWER SUPPLY FUSE PROTECTION
2.1.11.5 SHORT CIRCUIT CONTROL The NMC Pro incorporates a short circuit detection mechanism. When a short circuit is detected the NMC Pro performs a test procedure to detect the faulty outputs, generates an alarm indicating that a short circuit was detected and registers events indicating which outputs are faulty. The NMC Pro CPU uses the 24VAC current detector to measure the 24VAC current load and translates it to an A/D reading of 0-350. The short-circuit threshold is user-defined and depends on various parameters: 24VAC transformer size, number of devices to be operated simultaneously, power consumption per device, distance between controller to devices, cables dimension and resistance. When a short circuit is detected the system starts searching for the specific device that is causing it. The relay cards are shut down one after the other, starting from card no.8 down to card no.1. When a card with a short circuit is detected the relays are tested one after the other and those that have a short circuit are disabled. Once a short circuit occurs, an alarm is generated (one for all devices) and an event is registered for each device with a short circuit that is detected. Outputs that are short-circuited (marked “AL” in menu screen 5.1 RELAYS for NMC Pro Irrigation Software), are not turned on automatically and cannot be manually turned on. After fixing the short-circuit, reset the alarm in menu screen 3.1 ALARM RESET for NMC Pro Irrigation Software. The outputs will only become functional once the alarm is reset.

2.1.19 INPUT OUTPUT CARD LED INDICATION Several LED’s in the system can indicate a problem: CPU CARD LED - In normal operation the LED will blink to indicate a watchdog update. When the LED does not blinking for a few seconds the system will reset. If the LED does not resumed blinking it means there is a major failure, probably in the CPU board. OUTPUT CARD LED - In normal operation the LED will blink, every blink indicates that the main CPU updated the relays status and that communication between the cards are OK. In case of a malfunction in communication or power the LED will stop blinking. COMMUNICATION CARD LED - LED’s on communication card indicates communication between NMC Pro and PC / modem. When the LED’s are not blinking there is no communication between the NMC Pro and the PC / modem 2.1.20 INPUT OUTPUT CARD IDENTIFICATION
- After Cold Start, the controller resets cards data memory and re-searches 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 fails 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 3.1 ALARM RESET the controller turns off the alarm and refers to the missing card as
non-existent. - 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 with every power-up and adds the new cards to the list. The new cards are now considered as cards that must always be present.
- Alarms for cards do not reset automatically. Reset the alarm manually from the controller or the PC
