- Page 6 Operation Manual 1. INTRODUCTION The H2scan GSAO-2 Control Hub serves as a unified alarm and power supply system for GRIDSCAN® hydrogen multi- sense monitors and sensors that detect other environmental conditions. With four low-power alarm relays NO/NC or user-configurable to support hydrogen alarm, temperature alarm, moisture alarm, pressure alarm, and power status, the control hub supports one hydrogen sensor for transformer applications on the RS-485 loop.
- Page 7 3. INSTALLATION 3.1 MOUNTING The GSAO-2 Control Hub can easily be mounted to panels, plates, Unistrut, or wedge anchors into concrete and masonry. Alternately, H2scan provides a magnetic mounting plate as an accessory for purchase. For installation, refer to the included Quick-Start Guide.
- Page 8 Figure 3: Magnetic Mounting Plate (optional accessory) WARNING The GSAO-2 Control Hub weighs 3.4 kg (7.5 lb) and could be hazardous if dropped. Make sure the mounting is secure. CAUTION Proper grounding of the GSAO-2 Control Hub varies by installation and is the responsibility of the end user.
- Page 9 3.2.3 Closing the Lid 1. Tightly secure the screws to torque of approximately 1.13 N*m (10 in*lbf). Failure to tighten the cover screws can compromise the sealing of the GSAO-2 and may compromise the IP rating of the system. 2. Latch the cover.
- Page 10 5. Ensure the gasket is not pinched such that it bulges out of the cable gland flange. NOTE: If using conduit to route cables to and from the GSAO-2, the cable gland fittings and port plugs can be replaced by standard ½″ conduit gland fittings without modification to the enclosure. As the IP rating of the GSAO-2 is dependent upon the rating and construction of the conduit gland fittings, only use IP66 or better rated conduit gland fittings.
- Page 11 CAUTION Use cables or wiring with minimum temperature rating of 105 °C or equivalent. Do NOT pull secured cabling from the GSAO-2 as this can damage the connections. 3.5 WIRING Connect the GSAO-2 Control Hub with a multi-conductor cable that supports the desired configurations.
- Page 12 1. Remove the cable gland nut from the cable gland in the accessory kit. Ensure the mating rubber gasket is pushed all the way to the top of the threads. 2. Insert cable gland through preferred GSAO-2 hole. 3. Thread cable gland nut onto cable gland.
- Page 13 GSAO-2 Control Hub Operation Manual CAUTION Modification of the GSAO-2 enclosure to increase the size of the gland fitting ports is not recommended. It can compromise the IP rating of the system and void the warranty. 3.5.3 Hydrogen Monitor Wiring The cable used to connect to the GRIDSCAN®...
- Page 14 Figure 9: J8 Serial Communications Connector NOTE: When configuring the serial communications in the GSAO-2, the terminal resistor must be enabled only if the GSAO-2 is the last unit on the serial chain. Proper termination is required for the RS-485 communications to function properly.

Use an appropriately rated cable that meets the following specifications: •...
- Page 16 WARNING Do NOT apply AC voltage to a GSAO-2 Control Hub configured for DC voltage as damage to the GSAO-2 will occur. Failure to comply can cause a potentially hazardous condition, which will damage the unit and void the warranty.
- Page 17 Figure 13: DC Power Inlet NOTE: There is no accommodation for a ground wire with the line power cable within the GSAO-2 Control Hub. If the cable used has a ground wire, trim and do not connect it to the GSAO-2 Control Hub.
- Page 18 After all connections are made, flip the power switch in the Connector and Wiring Compartment to power on the GSAO-2 Control Hub. Upon startup, the GSAO-2 initiates its firmware and automatically detects the monitor. This could take up to 90 seconds. Upon detection, hydrogen monitor information appears on the display.
- Page 19 NOTE: For pressure, enter minimum and maximum set points. 15. Return to the Configuration Menu by pressing the left arrow key. 4.2.3 Relays The GSAO-2 relays can be configured for system power or an alarm that is configured for H level, temperature, moisture, or pressure.
- Page 20 4. Press the up and down keys to confirm no existing monitor configuration is saved in the GSAO-2. If the up and down keys reveal more screens, perform steps 1 and 3 again.
- Page 21 Operation Manual 5.2 DISPLAY The GSAO-2 display is always on. During normal operation, the GSAO-2 displays the following statuses with attribute, reading, and units of measure for approximately three seconds per screen before cycling to the next. • Hydrogen concentration (ppm) •...
