Step 5: Verify Wiring Connections; Step 6: Configuration - GE SVi 1000 Masonelian Quick Start Manual

Step 5: Verify Wiring Connections

NOTE
Use the following procedure to ensure that the SVi1000 is properly powered:
1. Connect a DC voltmeter across the input terminals.
2. Connect a milliampmeter in series with the current signal.
3. Verify that source can supply 20 mA to SVi1000 input. If 20 mA is not attainable,
troubleshoot the source.
NOTE

Step 6: Configuration

This section describes configuration using the local user interface pushbuttons. You can also use
ValVue and a PC with a HART
and the SVi1000" on page 51 describes ValVue software functions.
Prior to changing the SVi1000 configuration, check the existing configuration. Use the proce-
dures that follow to: run auto stops, run open stop adjustment and perform preset or auto tune.
WARNING
44 | =GE Oil & Gas
For split range installations the output voltage must be sufficient
to operate two positioners (11 V @ 4 mA, 9 V @ 20 mA) and the
expected voltage drop in the cable.
For an input current between 4 and 20 mA the voltage varies between 11V
and 9 V respective.
When voltage exceeds 11 V check that polarity is correct.
If voltage is less than 9 V and polarity is correct, voltage compliance of
current source is inadequate.
Improperly or inadequately grounded installations can cause
noise or instability in the control loop. The internal electronic
components are isolated from ground. Grounding the case is
unnecessary for functional purposes but grounding the case may
be necessary to conform to local codes.

These procedures can cause the valve to move. Before proceeding
ensure the valve is isolated from the process. Keep hands clear
from moving parts.
