OPERATING METHODS

The Hydran 201i System can be operated using several methods. Each of these methods is
explained in the following pages, from the simplest to the most powerful one:
• Periodic, visual monitoring: See Section 11.1.1 on page 11-1.
• Alarm monitoring: See Section 11.1.2 on page 11-2.
• Analog output monitoring: See Section 11.1.3 on page 11-3.
• Combined alarm and analog output monitoring: See Section 11.1.4 on page 11-4.
• Local monitoring with host computer: See Section 11.1.5 on page 11-4.
• Remote monitoring with host computer: See Section 11.1.6 on page 11-5.
11.1.1 Periodic, Visual Monitoring
Among the Hydran 201i System's operating methods, the periodic, visual monitoring is the
simplest. If used, the following routine must be an integral part of the on-site, station
inspection:
• Periodic, visual reading (once or twice a day) of the gas level reading on the display of
the Hydran 201Ti's or the Hydran 201Ci-1. For details on the various methods of data
reading, see Section 11.2 on page 11-5.
• On-site verification of alarms. For details on the alarms and relays operation, see
Chapter 10.
• Manual logging of the above results.
Only basic training to the station's personnel is required to implant this operating method.
When an alarm is detected, the operator must report the alarm and take the appropriate
actions for this type of alarm (follow the regulations and practices of the company).
