SHORT CIRCUIT 02 (Short line in MSTYA or MYOA input 2)
Cause
There is a short circuit between the entrance 2 of the MSTAY or MYOA and the end of
line resistance.
Solution
Verify the correct connection between the MSTAY, MYOA and the elements connected
to them, verify the end of line resistance, 33 K (see 1.5.3.4 and 1.5.3.7 chapters). The
tension of entrance 2 of the MSTAY for a correct operation must be included between -
5V and -7 V in rest.
TECHNICAL FAULT (IN2 input to the MSTAY has been activated)
Cause
A signal which is external to the digital detection system has activated the MSTAY IN2
input.
Solution
This is not a fault in the digital detection system; in fact this is how it should normally
work. Check the operating status of the devices connected to the MSTAY (IN2).
DIRTY SENSOR
Cause
The permitted level of dirt has been exceeded on the sensor (A30XHA, A30XHA-S and
A30XHTCO), 100% in the monitoring screen, the sensor must be cleaned.
Solution
Clean the sensor using compressed air reset the fault and monitors the element, checking
that the readings are below 5. If the levels are higher or the dirty sensor fault is repeated,
cleaning it has not been sufficient and it is recommended that the sensor is replaced with a
new one.
4.4.4.- OTHER FAULTS
ELEMENT NOT FOUND (In the monitoring screen)
Cause
The loop point indicated cannot be found by the control panel.
Solution
The element being monitored either has not been installed or else its programming
number has not been assigned. Check the element’s configuration.
REPEATER: XX IS NOT COMMUNICATING
Cause
There is a failure in communication with the indicated repeater.
Solution
Check the repeater’s connection to the control panel, check for short circuits and broken
wires, measure the repeater’s supply voltage to check that it is between 24V and 30V.
Check that the repeater’s number is correctly configured, making sure that the number
configured in the control panel is the same as the repeater's number. (see chapter 3.2.3.9)
CONTROL PANEL: XX IS NOT COMMUNICATING
Cause
There is a failure communication with the indicated control panel.
Solution
Check the connection of the control panel with the main control panel; check short
circuits, cut cables, check the correct operation of the control panel (see 1.5.5 chapter).
Check that do not exist two or more control panels with the same number.
