Section VI. Extended Capabilities Vl. Extended Capabilities The Operator's Station can be used to access extended capabilities of the PMS II, such as logging information on the printer, reading PMS status, deactivating sensors, and setting time and date for the PMS clock. These are all available by using the Edit mode. The following paragraphs will explain the extended capabilities, and how to use them, in detail. A. Edit Mode Operation To use the Edit mode, start by pressing the EDIT key. The EDIT keys on both Operator's Stations will light, locking all other users out of the Edit mode (pressing the EDIT key when someone at the other operator's station is in the Edit mode will have no effect), and instructions will be displayed on the video monitor. During each step of using the Edit mode, instructions, in the form of a menu of options, will be displayed on the screen. Using the Edit mode means simply following the instructions. There is nothing you can do that will cause any harm. The first thing to realize about the Operator's Station is that once the EDIT key is pressed, the keys on the keyboard have new functions. These functions are printed in black on the keyboard panel above the key. Therefore, the top left key has the value '1', Just like a calculator key. These secondary functions of the keys are used to perform the operations described below. Note: The system will -continue its monitoring functions even while the operator is using the edit mode. Should an alarm, or any other reason to return to the monitoring display occur, pressing the EXIT key will cancel all Edit mode operations and resume display of monitored points on the Operator's Station. 1. Option Selection As mentioned earlier, a menu of options is presented at each step in the Edit mode. Each option is numbered. Select the option by pressing the key with the same number as the chosen option. The PMS II will ignore any key not on the menu except EXIT. B. Logging The PMS II has the capability of logging information on a printer. This information includes the time and date, sensor and switch labels, alarm status, and sensor readings. One type of logging, Event logging, is automatic. The other two types of logging, Demand and Schedule logging, are controlled through the Edit mode. 1. Event Logging Event logging takes place every time an alarm is annunciated, acknowledged, or returns to normal. On the printer, each line will be tagged with either 'ALARM', 'ACK', or 'NORM' as appropriate to identify the event. PMS II Operator's Instructions Page 15
