11 4. INTERCONNECTION VM-55 INTERCONNECTION OF TRANSMISSION CABLE WITH VK SERIES Connection of signal transmission cable Do not use the blank terminals. Prohibition Mandatory For interconnection between the VK driver and the monitor, or between the VK driver and safety barrier, and safety barrier and monitor, make sure to use 3-core shielded cables or pair shielded standard 3-wire instrument cables, since the signal transmitted is weak. (Do not use unshielded cables or non-pair shielded multicore cables as the measured values could be affected by external noise.) Recommended cables Cable Recommended Note CVVS (3-core shielded cable) Conduit pipe Shielded wire INSTRUMENT CABLE (Pair shielded standard 3-wire) Conduit pipe Outside shielded Shielded wire Excellent Good Recommended cabling as per API st d 670 Normal: Silver-plated braid Recommended: Copper tape shielded (Core wire: Soft copper wire) Use conduit pipe (cable rack) for wiring. Although vibration and displacement signals can be transmitted in one instrument cable, use separate cables, because a high vibration signal exerts injurious influence over other displacement and vibration signals. Recommended: Outside shield of aluminum or copper tape. Provide separate cabling for pulse signals (phase marker, revolution) and for Mandatory displacement and vibration signals. Avoid running signal transmission cables together with control and power cables. Install all cables in conduit pipes or on cable racks. -4-

12 4. INTERCONNECTION VM-55 INTERCONNECTION OF TRANSMISSION CABLE WITH CV SERIES Connection of signal transmission cable Prohibition Mandatory Do not use the blank terminals. Use the exclusive cable for connection with the CV Series Velocity Transducer. Use a twisted pair, shielded cable with the specified cross section for connection between the junction terminal and monitoring device. Select suitable cable for operating environments. The cable length between CV Series Velocity Transducer and Monitor should not exceed 300 meters. Excessive length may limit the system s frequency response. Keep cabling away from power and control lines, to prevent noise interference. Cable should be securely fixed. Prevent the cable from bending sharply, twisting, kinking, knotting, and straining. The recommended minimum bend radius is 80mm. Shinkawa recommends that the cable should be routed through conduit to prevent physical damage and noise interference. -5-

29 5. DESCRIPTION OF FUNCTIONS VM POWER SEQUENCE If mounted in the VM-5G Single Unit Instrument Rack, the secondary power supply can be cut off by shorting between the P-S (POWER SEQUENCE) and COM terminals. Caution This function can be used for pulling out or pulling in the monitor unit at the emergency time. However, do not use for long time shorting of more than one (1) minute or turning on and off repeatedly. Also, the parallel connection for the two (2) or more monitors should not be allowed TIMED OK CHANNEL DEFEAT When on setting, when OK alarm is output, DANGER alarm, ALERT alarm, display, and recorder output are disabled. DANGER ALERT, display and recorder output are not disabled, in case of excessive signal input from sensor. For details refer to 7. PARAMETER SETTING on page SUPPRESSION FUNCTION This function can suppress the measurement around zero measurement point of the monitor by the effect of the piping vibration or electric noise, etc. during the machine stopping. The suppression can be set at 0.0 to 10.0 % (0.1% step) of the monitor range. ex.) If the suppression is set at 2.0%, monitor measurement less than 2.0% shall be output as 0.0%. -22-
