B-I INDUSTRIAL CO., LTD. SMOKE DENSITY INDICATOR 3-2-9 Positive Pressure Applications On oil fired boilers a pressure wave may be caused when the burner ignites disturbing soot accumulations and depositing them on the lenses. Therefore, the units should be located as far as possible from the actual flue gas outlet of the boiler.
Cable shields to be grounded only at control unit. Maximum cable length is governed by the total loop resistance of the core and should not exceed the following limits: Projector: 5 Ohms Receiver: 25 Ohms 4-20mA Analogue Output: 25 Ohms Wiring Diagram BI-SM2004.doc 23/34...
4-1-2 Main Connection The unit is normally supplied for 220V, 60Hz operation and, optionally, 110V, 60 Hz. For optimum performance the mains supply to the BI-SM2004 should never be interrupted. 4-1-3 Alarm Relays Alarm relays are rated at 5 Amps 250 V.A.C. non-inductive load and provide non-committed change-over contacts for external circuits.
