The Agility Controller requires a dedicated 120VAC power circuit. The Agility Controller contains a 10 amp fuse to protect both itself and any controlled devices.
Each digital output is also individually fused with a 4 amp fuse. Each digital output is rated for a maximum of 1.5 amps for a combined total of 9.5 amps.
Additionally the analog 24V and Com 2 +24V are protected with a self-resetting polymer fuses rated at 1/10
th
amp. When a polymer fuse is exposed to
over-current conditions, power must be removed before the fuse will reset.
Analog Sensor Troubleshooting
The safety message "Sensor Under-Range" indicates at least one sensor is sending an excessively low signal (under the normal operating range) to the Agility
panel. Typically causes of a low signal are a broken wire or damaged sensor.
The safety message "Sensor Over-Range" indicates at least one sensor is sending an excessively high signal (over the normal operating range) to the Agility
panel. Typically causes of a over-range signal are a shorted wire or damaged sensor. A faulty sensor will display a series of question marks instead of a normal
sensor reading. View I/O Status to ascertain which sensor is faulting. Moisture penetration into a sensor's enclosure is the most common source of sensor
failure. Refer to the sensor installation wiring diagrams for installation information.

M24VDC supply at the
sensor. The voltage should be near
+24VDC.
1. The +24VDC Power wire is shorted to the Common
(shield) wire. An Automatically Resettable fuse protect
the sensor's +24VDC power. The cause of the short
must be removed 24VDC power will be
restored. In some cases, the Agility controller must be
powered-down for approximately 5 seconds.
2. Break in supply wire to sensor.
3. The sensor supply is wired incorrectly. The sensor
should be supplied by +24VDC power from the "Pwr"
terminal. Review the wiring diagram and correct any
wiring errors.
4. The A24VDC supply is faulty. Replace the Agility
controller assembly.

(continued).
Measure the signal wire from the
sensor. It should be between
+0.5VDC and +3VDC
(approximately).
1. Sensor is bad if voltage is not b0.5VDC and
+3VDC, often from water damage. Replace Sensor if
signs of corrosion are present.
2. Signal wire is broken or disconnected if voltage is near
zero.
