Specications
Precautions
Observe these precautions when installing Checker to reduce the risk of
injury or equipment damage:
Do not use Checker in applications where an incorrect or absent
output signal could cause human injury.
Checker is intended for indoor use only.
Do not attempt to adjust Checker’s focus when moving parts and/or
equipment are present.
Use a listed power supply with an output rated 24 VDC, at least 250 mA, and
marked Class 2, Limited Power Source (LPS). Any other voltage creates a
risk of re or shock and can damage Checker.
Connect the cable shield (or ground screw, if using the I/O module) to earth
ground.
An IP67-compliant plug or cable must be tted to the USB connector for
Checker to meet the IP67 protection standard.
Do not install Checker in locations that expose it to environmental hazards
such as excessive heat, humidity, impact, vibration, corrosive substances,
ammable substances, or static electricity.
To reduce the risk of damage or malfunction, route all cables and wires away
from high-voltage power sources.
Make sure that the mounting screws do not bottom in the mounting holes;
using too long a mounting screw can damage Checker.
Do not attempt to modify Checker. Modications will void the warranty.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
