ROC827 Remote Operations Controller

ROC827 Instruction Manual

Caution

Check the input power polarity before connecting power to the ROC827.

Incorrect polarity can damage the ROC827.

When working on units located in a hazardous area (where explosive gases may be present), make sure the area is in a non-hazardous state before performing procedures. Performing these procedures in a hazardous area could result in personal injury or property damage.

2.8.1 Startup

Before you apply power to the ROC827, assess the power requirements

(including the base unit, EXPs, and any installed modules and peripheral devices) that comprise the total configuration for your ROC827. Refer to

“Determining Power Consumption” in Chapter 3, Power Connections.

Apply power to the ROC827 (refer to “Installing a Power Input Module” in Chapter 3, Power Connections). The power input BAT+ LED indicator should light green to indicate that the applied voltage is correct. Then, the

STATUS indicator on the CPU should light to indicate a valid operation.

Depending on the Power Saving Mode setting, the STATUS indicator may not remain lit during operation (refer to Table 2-2).

2.8.2 Operation

Once startup is successful, configure the ROC827 to meet the requirements of the application. Once it is configured and you have calibrated the I/O and any associated Multi-Variable Sensors (MVS,

MVSS, MVSI, and so on), place the ROC827 into operation.

Caution

When working on units located in a hazardous area (where explosive gases may be present), make sure the area is in a non-hazardous state before performing procedures. Performing these procedures in a hazardous area could result in personal injury or property damage.
