Module Connection
| DANGER | |
|---|---|
HAZARD OF ELECTRICAL SHOCK, EXPLOSION OR ARC FLASH Switch off the sensor and pre-actuator voltages before
connecting or disconnecting the module. Failure to follow these instructions will result in death or serious injury. | |
| CAUTION | |
|---|---|
LOSS OF INPUT FUNCTION Install the correct rating and type of fuses. Failure to follow these instructions can result in injury or equipment damage. | |
The diagram below shows the connection of the module to the sensors and pre-actuators.
input power supply: 24 VDC
output power supply: 24 VDC or 24...240 VAC
input fuse: 1 fast blow fuse of 0.5 A
output fuse: 1 fast blow fuse of 12 A
pre-act: pre-actuator
Sensor Power Outage
After a power sensor outage, if the check box is not selected in the module configuration screen then the digital input can stay active.
| WARNING | |
|---|---|
DIGITAL INPUT STATE INACTIVE AFTER A SENSOR POWER OUTAGE Do not click to clear the check box in the module configuration
screen to guarantee the digital input state inactive after sensor
power outage. Failure to follow these instructions can result in death, serious injury, or equipment damage. | |
To access the check box, refer to chapter How to Modify the External Power Supply Error Monitoring Parameter.
After the sensor power outage, the I/O (red) LED of the module switches on and the last recorded position of the sensor is displayed by the input channel status LED's.
