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 shortcircuit, 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.

2.1.13.1 DESCRIPTION
Each NMC 64 / Pro I/O Bus Card comprises a maximum of 8 output cards, 5 of which can be 24VAC
output cards. Each output card consists of 8 outputs which gives a total of 40 x 24VAC outputs per I/O
bus card.
The remaining 3 slots can be filled with dry contact output cards, which can also be configured for
24VAC outputs, please see NMC 64 / PRO DRY CONTACT OUTPUT CARD section NMC 64 / PRO DRY
CONTACT OUTPUT CARD CONNECTION FOR 24VAC OUTPUTS.
NB
NMC 64 / PRO 24VAC OUTPUT CARDS can only be connected to the right hand side
output slots of the I/O bus card.
The 24VAC output card is used to drive devices that require a 24VAC power supply. The top terminals
of the card consist of the common connections and the bottom terminals of the output connections.
It is possible to connect the commons of several devices to the same connector. However it is
recommended to try and spread the commons in an even manner between 24VAC output cards.
The 24VAC output card includes surge and lightning protection circuits and does not require
additional external protection under normal conditions.

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.

2.1.19 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.
