MAG 5000 P42 NO LOAD ON CURRENT OUTPUT ERROR

42

P42 - Current output
Check cables

Current loop is disconnected or the loop resistance is too big

Not a very precise diagnostic, but it does seem that your wiring is causing the problem, make sure everything is well connected and tightened. Come back to the forum if nothing seems to help or if any other message appears.

8.1 Output settings

Three outputs are available:

Current output (range and time constant); terminals 31 and 32.

Digital output (pulse, frequency, error, limit, or batch settings); terminals 56, 57, and 58.

Relay output (error, limit, and batch settings); terminals 44, 45, and 46.

Current output

In the current output menu it is possible to select current output range and time constant, see also Current output menu diagram (Page 79).

If current output is set to "4-20 mA+Alarm", the current output will show the following mA:

1.3 mA (if error level is "Fatal").

2 mA (if error level is "Permanent").

3 mA (if error level is "Warning").

For setting of error level, see error level menu diagram (Page 80).

If current output is not used, it must be set to "Off".

8.5 Service mode

All outputs of the transmitter can be forced-controlled in the service mode menu, see also service mode menu diagram (Page 87).

Here it is possible to check whether e.g. the current output is functioning.

Error pending and status log lists are also accessible from this menu and the operating time (in days) can be read.

The forced control is cut off and all previous settings are reinitialized the moment the service mode is left by pressing top up key.

Just to confirm things... it sounds like you have a remote indicator that is connected to the mag5000 analog output, is this so? If that's the case does the Mag5000 display indicate flow is going through the meter but your remote display does not?

If so, it sounds like only a broken wire between the two units.

You should be getting somewhere between 4 and 20 milliamps from the unit. If you have a multimeter you can try putting it in series with your remote indicator to get a reading in DC mA. You can't do it at the flow meter directly as the terminals are under the electronics / display unit.

Good luck!
