Info

Display and functions do not work properly. Is the input free of noise? YES Contact your nearest Sales & Service center Panel key does not work properly. Is the key-lock unlocked? YES Contact your nearest Sales & Service center NO NO Ground the recorder properly. Use shielded wire for input and communication. Insert an isolated transformer into the power line. Insert a power line filter into the power line. In case a reactive road is used as an alarm output line, use a surge suppressor in the alarm line. Separate the input & communication wires from the noise generating wire. Insert the key (see 5.4). Set the key-lock to NOT USE in the SET UP Mode (see 9.10). 12 - 4 IM 4H3B1-01E
TERMINOLOGY allowable input voltage The maximum input voltage that can be applied to the input terminals burnout Failure of a device due to excessive heat common-mode rejection ratio The ability of an amplifier to cancel a common-mode voltage common-mode voltage A voltage that appears equally and in phase from each signal conductor with respect to ground. Also known as common-mode noise. Power noise induced from a power transformer is a typical example of this noise (voltage) dead band In static characteristics, the range through which an input signal can be varied without initiating an observable change in output signal DI Digital Input (contact & voltage level) dielectric strength The potential gradient at which electric failure or breakdown occurs EMI An abbreviation for Electromagnetic Interference. Impairment of a wanted electromagnetic signal due to an electromagnetic disturbance error Any discrepancy between a measured quantity, set-point, or rated value and the ideal value of the measured signal hysteresis An effect wherein a given value of a parameter may result in multiple values input resistance Resistance measured at the input terminals of an instrument under operating conditions input source resistance Resistance of the measuring circuit outside the instrument ISO An abbreviation for International Organization for Standardization noise An unwanted disturbance superimposed upon an indicated or supplied value, which obscures its information content normal mode rejection ratio The ability of certain amplifiers to cancel a normal mode noise, usually expressed in decibels normal mode voltage An unwanted input (noise) voltage superimposed on the measurement voltage reference junction That thermocouple junction which is at a known or reference temperature reference junction compensation A means of counteracting the effect of temperature variations of the reference junction, when allowed to vary within specified limits reflash Function to indicate repeating alarm occurences among a group of alarms sharing the same output relay resistance temperature detector A detector for measuring temperatures with a change in electrical resistance that is a known function of temperature resolution The minimum detectable change of some variables in a measurement system, or a minimum change in supplied quantity that can be set RS-422-A The EIA (Electronics Industries Association) approved standard, which established the requirements for serial communications between computers IM 4H3B1-01E Terminology - 1 TERMINOLOGY
