Page 4: Introduction
The GSAO-1 is powered with nominal 9 to 48 VDC, which is passed through to the GRIDSCAN 5000 Hydrogen Sensor System. Only two cables are required; one to connect the GSAO-1 Module to the GRIDSCAN 5000 Hydrogen Sensor with power and communications, and one from the customer supplying DC power and taking the analog signal out to the customer’s data... -
Page 5: Features
The GSAO-1 Analog Output Module has a rugged waterproof and dustproof mechanical assembly design for various transformer applications. The enclosure is easily mounted using the four mounting holes and the included #10 18-8 stainless steel screws. The GSAO-1 is rated IP68 and can be used in most environments. -

5 mm to 12 mm (0.20” to 0.47”) Outside Diameter jacketed cables. If it is desired to utilize conduit to route cables to and from the GSAO-1, the cable gland fittings can be replaced by standard ½” conduit gland fittings without modification to the enclosure. The IP rating of the GSAO-1 is dependent upon the rating and construction of the conduit gland fittings. -
Page 13: Cables
The cable used to connect to the GRIDSCAN 5000 Hydrogen sensor is an orderable option available in various lengths. If the cable is not ordered from H2scan, it should be rated for the environmental conditions it will be used in. A suitably rated cable assembly is required for most field applications. -
Page 14: Wiring Connections
Do NOT unplug or plug wiring connectors when the system is energized. 8.3.1 Earth Grounding the GSAO-1 Module An earth ground is required to be connected to the case of the GSAO-1 Analog Output Module. It should be added in conjunction with the mounting hardware. (See Section 7) With the grounding clip securely installed with the GSAO-1 mounting, insert the bare grounding wire into the clip and tighten the set screw. -

GSAO-1 Operating Manual 8.3.2 GRIDSCAN 5000 Hydrogen Sensor Wiring Connections After connecting the cable to the GRIDSCAN 5000 sensor, route the cable to the GSAO-1. Secure cable as necessary. Trim the cable to length so that there will be approximately 160 mm (6.5 inches) inside of the GSAO-1 module when assembled. -
Page 16: Customer Wiring Connections
Two conductors should be used for DC power, and two for current loop analog output. After routing the cable to the GSAO-1 installation, trim any excess cable so that approximately 210 mm (8.5 inches) of cable will be inside the GSAO-1 module. - Page 17 GSAO-1 Operating Manual After all wires are stripped, insert the cable through the left gland fitting on the GSAO-1 enclosure so that 10 mm (½ inch) of the cable jacket is visible inside the enclosure above the gland fitting. Securely tighten the gland fitting to the cable using an adjustable wrench. 0.28 N*m (2.5 in*lbf)

Page 21: Configuration Mode
Damage to the switches can affect the operation of the GSAO-1 module and may void the warrany. The GSAO-1 Analog Output Module has a configuration mode where the oil type can be changed, the scaling of the analog output can be changed, and the analog output can be tested. -

GSAO-1 Operating Manual However, if the serial number is different, the GSAO-1 will enter a service condition. This is indicated by the Blue LED blinking 3 times every 12 seconds. It is assumed that if the sensor is changed or the GSAO-1 is relocated to another installation site, that the configuration would need to be changed. -
Page 24: Test Mode
(7131). The default mode is for Mineral oil. The LED below the switches indicates which oil type is configured. When the GSAO-1 is set to configuration mode, the oil type can be changed by moving the switch above the desired oil type from the bottom to top position using the provided golf tee. The switch for the previously selected oil type should be then moved from the top to the bottom position. -
Page 25: Analog Output Scaling
The GSAO-1 Analog Output Module has the ability to report an analog output signal up to 24 mA. However, signals between 20 mA and 24 mA exceed the selected 4-20 mA scale and the GSAO-1 should be reconfigured for the appropriate scale. -

LEDs, through “OIL | GAS”, and through the oil type LEDs ending with “MINERAL” being the last to illuminate. During the delay before the LED sequencing, the GSAO-1 configuration is stored in non-volatile memory and 90000180 Rev 2, 2/27/2025... - Page 27 If the GSAO-1 configuration mode is disabled by turning the “CFG” switch OFF and there are NO errors with oil type, the new configuration is stored in the GSAO-1 and is implemented in the Hydrogen sensor. The new configuration is then indicated by the oil type LED.
