Qlarity-Based Terminal Hardware
For information on downloading new firmware, downloading a user application, and determin-
ing the size of a user application, refer to the Qlarity Foundry User Guide.
1.3.7 Watchdog Timer
A watchdog timer can be added to enforce proper operation of the QTERM-G70. The watch-
dog timer will reset the terminal if there is a problem that causes the firmware to lock up. This
does not apply to software deadlocks in the Qlarity code. If that is required, then the Qlarity
watchdog timer should be used, using the WatchdogEnable and WatchdogReset APIs.
1.4 Installing to NEMA-4
A QTERM-G70 terminal uses a rugged, glass-filled polyester (UL 94V-0) case designed to
mount into a panel or drywall. When properly installed in a NEMA-4 rated panel, the
QTERM-G70 meets all NEMA-4 specifications including hose-down, icing, and salt spray.
A QTERM-G70 terminal can be installed in either a landscape or portrait orientation. When
installing a terminal, you generally take the following steps.
• Decide whether you want to mount and use the terminal in a portrait or landscape orienta-
tion. “Portrait” means that the longest dimension is vertical; “landscape” means that the
longest dimension is horizontal.
• Cut a hole in the panel or drywall. See section 1.4.1, “Cutout for Panel Mount Configura-
tion” or section 1.4.3, “Cutout for Drywall Mount Configuration” for specifications.
• Install the QTERM-G70 terminal in the panel or drywall. See section 1.4.2, “Installing the
Panel Mount Terminal” or section 1.4.4, “Installing the Drywall Mount Terminal” for
instructions.
• Connect cables to the terminal. Verify that the thumb screws are tight or the locks snapped
into place for each cable used.
• Apply DC power to the QTERM-G70 terminal. See section 1.4.5, “Applying Power” for
information.
1.4.1 Cutout for Panel Mount Configuration
The QTERM-G70 terminal can be mounted in panels from 0 to 7 mm thick. No screw holes
need to be drilled to install the terminal in the panel.
Make a rectangular hole in the panel using the following dimensions.
Landscape Portrait
Horizontal: 199 ± 1 mm Horizontal: 145 ± 1 mm
Vertical: 145 ± 1 mm Vertical: 199 ± 1 mm
