Simtronics GD10-P00 - Parameter Configuration and Diagnostics

GD10P User Manual Page 23 of 44 850-811250-Rev.06b
5.2.4.8 SET FAULT OPTION (Detailed setup)
The operator can choose between three options according to the following table.
Option
Detector fault
Dirty Optics
Early Dirty Optics
(see note 1)
OP0
(default settings)
<0.5 mA
1 mA
2 mA
OP1
1 mA
2 mA
3 mA
OP2
(User selectable)
1 (0 mA)
2 (1 mA)
3 (2 mA)
4 (3 mA)
1 (0 mA)
2 (1 mA)
3 (2 mA)
4 (3 mA)
1 (no warning)
2 (1 mA + pulsing)
3 (2 mA)
4 (3 mA)
Note 1: If in “Early Dirty Optics” state, the detector will switch to standard output level when
gas reading is >7% of detection range.
After a reconfiguration, it is recommended to restart the detector and verify the new settings by
simulating different alarm/warning states. A current meter may be used to read the level at the
analogue output.
5.2.4.9 PV unit (Detailed setup)
The operator can choose between several measurement units. Default is “%LEL”.
5.2.4.10 GD10 Zero Trim (Diag/Service)
This function should be activated by special trained operators. If zero trimming is not
done in a controlled way, the performance of the detector can be reduced. Also, prior
to launching this function, read the detailed descriptions in section 6.4.
When this function is activated, the operator gets on-line instructions on how to support the
function. The analogue output will drop down to 1mA to indicate the on-going zeroing process,
which takes about 3-4 minutes to complete. The analogue output returns to the actual zero
(4mA) when zeroing process is completed. Zeroing will not take place if the ambient temperature
is outside a specific temperature range (around 20 – 30 deg C). If the Zero level is not improved
after the zeroing, the reason is that the zero drift is over the allowed limit for field trimming.
