 Four Contact Inputs ( Dry switches)
 Two 4–20 mA outputs (Cal A and Cal B)
 One Common Alarm Dry Contact Output
 One Contact Input (Dry switch) to force the temporary activation
of the High Calibration
Note Normally there are two possible modes of validation. The local validation
routes the validation gases from the switching panel to the SOLA II Flare. The
remote validation routes the validation gases to the probe and back to the
switching panel as the normal flare sample. ▲
Five pneumatic outputs from the SOLA II Flare can drive a sample select valve:

Flare Sample

Low Gas

Mid Gas
 High Gas
 Local / Probe selection
Two Relay Outputs can be used during the probe validations to drive signals to
the Probe Box
See Relays 5 and 6 on the I/O Table.
The SOLA II Flare can be commanded to select any of the following possible
states:
0. Normal Flare Monitoring (auto-range)
1. Local Low Gas Cal A
2. Local Low Gas Cal B
3. Local Mid gas Cal A
4. Local Mid gas Cal B
5. Local High gas Cal B
6. Probe Low Gas Cal A
7. Probe Low Gas Cal B
