2.1.11.4 FUSE PROTECTION

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.

2.1.14 OUTPUT CARD - DRY CONTACT 2.1.14.1 DESCRIPTION Each NMC 64 / Pro I/O Bus Card comprises a maximum of 8 output cards, all (or some) of which can be dry contact output cards. Each card comprises 8 outputs which gives a maximum of 64 x dry contact outputs per I/O bus card. The dry contact output card can be used to drive devices of various voltages depending on what is connected to it. The 8 outputs per card are isolated from each other and are normally open. With the activation of an output, the normally open contact will be closed and there will be continuity between the terminals for only that output. If more than 40 outputs for 24VAC are required, dry contact output cards can be configured to supply additional 24VAC outputs. The dry contact output card includes surge and lightning protection circuits and should not require additional external protection under normal conditions. 2.1.14.2 SPECIFICATIONS

• 8 x Normally Open relays per card • Relay output rating 5A at 24VAC • Relay switching rate 0.4 seconds

2.1.17.2 NMC PRO DATA PLUG

The NMC Pro Data Plug is used to backup controller settings and configuration. FOR NMC PRO USE GOLD (YELLOW) DATA PLUG. The NMC Pro Data Plug is not polarity dependant and can be installed either way round.

2.1.18 NMC PRO OUTPUT LICENCE KEY

NMC Pro Output License Key is used to make 64 outputs available for NMC Pro controller when using SA Radio Serial Interface. The NMC Pro Output License Key is fitted to the NMC Pro CPU, please see NMC PRO CPU CARD.


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
