Troubleshooting
The following section is designed to help you isolate the most likely system malfunctions that may occur.
For additional help, contact Quest’s Technical Support and Service
Center.
10.1
Power Up
PROBLEM
▪
Green Power Light is not blinking every second.
SOLUTION
1)
Use a volt meter and verify that the incoming power to the MP2 is between 18 and 65VDC.
2)
Verify input power polarity. If using an A&B feed, make sure both feeds have correct polarity.
3)
Replace the MP2
10.2
Communication
PROBLEM
▪
I experienced a communication failure with the TELSEC
®
MP2 through my Ethernet connection.
SOLUTION
1)
Verify you have a physical link by looking at the Green LED on the Ethernet jack. Reconnect or
replace any defective IP/Ethernet cables.
2)
Verify the router the TELSEC
®
MP2 is connected to is operable and properly configured.
3)
Verify the IP address has not been changed. Connect to the TELSEC
®
MP2 with a crossover cable
using the programmed address or try the default address of 192.168.1.31
4)
Replace the Ethernet cable.
5)
Power cycle the MP2
10.3
Sensor Reading
PROBLEM
▪
I am not receiving data from one of my sensors.
SOLUTION
1)
Verify wiring is correct from the sensor to the TELSEC
®
MP2.
2)
Use a known good sensor and replace the suspected bad sensor.
3)
If the known good sensor doesn’t work, then disconnect the field wiring from the
TELSEC
®
MP2
and connect it directly. If it works now, then correct or replace field wiring.
4)
If the known good sensor doesn’t read when connected directly to the
TELSEC
®
MP2 then try
the sensor on another input. Be sure to define the input accordingly.
5)
If the input is bad the TELSEC
®
MP2 is bad then either move the sensor to a spare input or
replace the unit.
10.4
Control Point Failure
PROBLEM
▪
One of my control points is not turning off.
SOLUTION
1)
Verify that the program is correct and has the proper program assigned to the output.
