EL3692 default setting
The default state for both EL3692 channels is
• CoE mode (parameter settings via CoE)
• alternating measuring mode
• 4-wire mode
• Autorange for the measuring ranges
• Process data: fixpoint and float
• Filter setting 10 Hz (approx. 100 ms conversion time)
• Delay time 10 (200 or 500 ms depending on the measuring range)
Time behavior in Autorange mode
In standard measuring mode the EL3692 keeps switching between the two channels. De-
pending on the connected measuring object significant charging effects may occur, which
Note
may not be completed within the specified measuring time. In Autorange mode, with signifi-
cant changes in resistance and associated changes in measuring range, this may result in
the correct measuring range not being reached, which would impair the measuring accu-
racy.
By extending the delay before the measurement, sufficient time for charging processes can
be made available to ensure that the correct measuring range is reached in Autorange
mode. Should the automatic setting be inadequate, the user can change the measuring
time in the CoE, 0x80n0:31 [} 132].
Step-by-step instructions
Proceed as follows for commissioning with the above-mentioned settings:
1. Install the EL3692 as described in section Installation and wiring [} 25].
2. Activate the EtherCAT master and start the terminal in OP state. In the input variables the EL3692
must supply state=OP and WC=0.
3. Connect the resistance in 2-wire or 4-wire mode according to the figure below
