Page 5: Sitrans Lu Sam
The SITRANS LU SAM is to be used only in the manner outlined in this instruction manual. The SITRANS LU SAM Satellite Alarm Module is used to provide up to 20 relay outputs for the scan points of the associated main electronics. Normal operation of the SITRANS LU SAM is programmed at the main electronics. -
Page 6: Installation
Installation shall only be performed by qualified personnel and in accordance with local govering regulations. • Do not mount the SITRANS LU SAM in direct sunlight without the use of a sun shield. • This product is susceptible to electrostatic shock. Follow proper grounding procedures. -
Page 7: Layout
Relay contact terminals are for use with equipment having no accessible live parts and wiring having insulation suitable for at least 250 V. The maximum allowable working voltage between adjacent relay contacts shall be 250 V. 7ML19985CF02 SITRANS LU SAM – INSTRUCTION MANUAL Page 3... -
Page 8: Switch Setting
Set the bank / LU SAM selection switches ( SW1 - 1 & 2 ) located at the upper right hand corner of board ‘ A ’ in order to enable the SITRANS LU SAM corresponding to the points being addressed. -
Page 9: Sitrans Lu 10 Communication
SITRANS LU SAM interconnecting cable shield should be grounded at applications device only. Insulate shields at junctions to prevent inadvertent grounding. * If SITRANS LU SAM is unpowered, transmitter ceases communication to all downstream peripherals. Maximum individual loop length 3000 m (10,000 ft) with specified cable. -
Page 10: Relay Output
• A circuit breaker or switch in the building installation, marked as the disconnect switch, shall be in close proximity to the equipment and within easy reach of the operator. Page 6 SITRANS LU SAM – INSTRUCTION MANUAL 7ML19985CF02... -
Page 11: Operation
Test overrides the normal operation of all 20 relays. The status LEDs sequentially flash on and off until switch 6 is reset (0) for normal operation of the SITRANS LU SAM. During test, the SITRANS LU SAM buffer is updated if communication has continued. Upon resumption of normal operation, the relays and LEDs assume the status found in the buffer. -
Page 12: Maintenance
Maintenance The SITRANS LU SAM requires no maintenance. However, a program of periodic checks is recommended. This should include regular inspection, general cleaning and good housekeeping practices. The enclosure and circuit boards should be cleaned only when power is disconnected at the main breaker, using a vacuum and clean, dry paint brush. - Page 13 Notes...
