Page 10: General Considerations
Handling, Installation and Case Dimensions HF9024 1. GENERAL CONSIDERATIONS 1.1 Receipt of relay Protective relay, although generally of robust construction, require careful treatment prior to installation on site. Upon receipt, relay should be examined immediately to ensure no damage has been sustained in transit. If damage has been sustained during transit a claim should be made to the transport contractor and HAMIANFAN should be promptly notified. -
Page 11: Handling Of Electronic Equipment
Handling, Installation and Case Dimensions HF9024 2. HANDLING OF ELECTRONIC EQUIPMENT A person’s normal movements can easily generate electrostatic potentials of several thousand volts. Discharge of these voltages into semiconductor devices when handling electronic circuits can cause serious damage, which often may not be immediately apparent but the reliability of the circuit will have been reduced. -
Page 12: Relay Mounting
Handling, Installation and Case Dimensions HF9024 3. RELAY MOUNTING The relay is dispatched either individually or as part of a panel/rack assembly. Modules should remain protected by their metal case during assembly into a panel or rack. For individually mounted relays an outline diagram is supplied in following of this chapter showing the panel cut-outs and hole centers. -
Page 13: Unpacking
Handling, Installation and Case Dimensions HF9024 4. UNPACKING Care must be taken when unpacking and installing the relay so that none of the parts is damaged or the settings altered. The relay must only be handled by skilled personnel. The installation should be clean, dry and reasonably free from dust and excessive vibration. -
Page 14: Storage
Handling, Installation and Case Dimensions HF9024 5. STORAGE If relay is not to be installed immediately upon receipt they should be stored in a place free from dust and moisture in their original cartons. Where de-humidifier bags have been included in the packing they should be retained. The action of the de-humidifier crystals will be impaired if the bag has been exposed to ambient conditions and may be restored by gently heating the bag for about an hour, prior to replacing it in the carton. -

User Guide HF9024 Password entry The input of the password is requested as soon as a modification of a parameter is made for any one of the six/eight menus and the submenus. The user enters each one of the 4 characters and then validates the entire password with enter keypad. - Page 24 User Guide HF9024 MENU The menu of HF1021relay is divided into main menus and submenus. Default display By default, the LCD displays the current value measured. As soon as an alarm is detected by the relay, that information is considered as more important and the alarm message is then displayed instead of the default value.
