PROBLEM SOLVING
In this appendix, several problems are included that can occur when the E115-P is going to be installed or while
it is in operation.
Flowmeter does not generate pulses
Check:
• Signal selection SETUP 6.1 / 6.2.
• Pulse amplitude (paragraph 4.6.3).
• Flowmeter, wiring and connection of terminal connectors (paragraph 4.6.3).
• Power supply of flowmeter (paragraph 4.4.2).
Flowmeter generates "too many pulses"
Check:
• Settings for Total and Flowrate.
• Type of signal selected with actual signal generated.
• Sensitivity of coil input.
• Proper grounding of the E115-P, avoid ground loops.
• Use screened wire for flowmeter signals and connect screen to the ground input terminal of the
flowmeter input.
Analog output does not function properly
Check:
• SETUP 7.1: is the function enabled?
• SETUP 7.2 / 7.3: are the flow-levels programmed correctly?
• SETUP 7.5 / 7.6: are the 4mA and 20mA tuned correctly?
• Connection of the external power-supply according to the specification.
Pulse output does not function
Check:
• SETUP 8.1 - mode: is the correct function selected?
• SETUP 8.2 - impulse width: is the external device able to recognize the selected pulse width and
frequency?
• SETUP 8.3 - amount per “x” quantity: is the value programmed reasonable?
Flowrate displays "0 / zero" while there is flow (total is counting)
Check:
• SETUP 2.1 / 2.4 / 6.8 / 6.9: are the K-factors and time unit correct?
• SETUP 2.5 / 2.6: The unit has to count the number of pulses according to SETUP 2.5 within the time
according to SETUP 2.6. Make sure that SETUP 2.6 is set to 10.0 seconds for example: the result is
that the unit has at least 10 seconds time to measure the number of pulses according to SETUP 2.5.
The password is unknown
If the password cannot be retrieved, there is only one possibility left: call your supplier.
ALARM
When the alarm flag starts to blink an internal alarm condition has occurred. Press the "select button" several
times to display the error code. The codes are:
[d] 1 = display error
[d] 2 = data-storage error
[d] 4 = initialization error
[d] 16 = IO configuration error base
[d] 32 = IO configuration error interface
[d] 128 = Automatic K-factor conversion error
When multiple alarms occur, the error code shown is the sum of the error codes as given above.
E.g. 0048 is a combination of error code 0016 and 0032.
If the alarm occurs more often or stays active for a long time, please contact your supplier.
