4-1.6.2 Performing Initial Tests

Because of the Genesis II System’s flexibility, the various configurations can be vastly dierent

from each other. For this reason, it is not practical to provide detailed procedural instructions for

performing initial tests that apply to all configurations. However, this paragraph describes the

general methodology for performing the initial tests.

Initial tests using the Gen2Mon Soware are divided into three separate phases; these tests should

be performed on each controller in turn:

• In the first phase of testing, power is removed from all output circuits and the Gen2Mon soware

is used to monitor the states and input/output values of the various configuration blocks using

variable input stimuli. This phase serves two purposes: It checks the configuration of the

controller and it helps to familiarise the operator with the operation of the system.

• In the second phase of testing, the controller’s primary output circuits, such as motor controllers

and relay circuits are energised but the output machinery (fans, pumps, compressors, etc.) are

de-energised. In this phase, the controller inputs are stimulated just enough to cause the output

circuits to operate or change state. This phase checks the operation of the output control circuits

without operating the plant machinery.

• In the third phase, the primary output control circuits as well as the plant machinery are

energised. In this phase the controller inputs are carefully stimulated just enough to briefly test

the operation of the plant machinery. This phase should involve the minimum of controller input

stimulation required to operate the machinery.

4-1.6.3 First Phase Testing

Perform the first phase of initial tests of the system as follows:

1. Turn o all electrical power to the Genesis II System.

2. Connect the controller to the PC by finding it on a connected network, connecting an RS232

cable between the controller’s RS232 connector and the computer’s serial port or by connecting

an RJ45 cable between the controller's RJ45 connector and the computer's.

3. Turn on the computer and allow it to boot-up. Turn on the controller’s operating power. All

output circuits should be de-energised at this time.

4. Using standard Windows procedures, open the Gen2Mon folder.

5. Click on the Gen2Mon icon to open the Gen2Mon program. The Gen2Mon screen is displayed.

6. In the Simulation Mode, carefully adjust the controller’s input parameters, such as temperature,

pressure, switch position, etc. Adjust the values within normal and practical operating limits

and just enough to verify that a realistic change in output is produced.

7. When all inputs and outputs have been checked, return the input parameters to their original

settings. The first phase is completed.

Operation of the GEN2MON soware in the simulation mode presents a serious risk to the system. In the simulation

mode, the operator is actually forcing values into the controller, therefore, it is possible to overcome any of the

natural safeguards which may be in place to protect the plant. When in simulation mode, exercise great care in

adjusting values. The soware is a powerful facility and should not be used carelessly.
