14 Chapter 2 Chapter 2 Overview of Temperature Monitor Module Overview of Temperature Monitor Module The Temperature Monitor Module monitors the temperature of each part of the rotating machine. It is capable of receiving input from up to six channels. In other words, a single monitor can monitor temperature at six locations. Supported input transducers include: thermocouples, three-wire type resistance thermometer bulbs and four-wire type resistance thermometer bulbs. Also, this module provides the recorder output corresponding to input signals and contact output, to outside equipment via the rear panel of the instrument rack. 2.1 Functions This section provides the basic description of the measurement function, display function, alarm function, output function and control function provided by the module Measurement Function Measurement Value Calculation The temperature detected from input signals is output as a measurement value Display Function Indicators on the Front Panel The indicators on the front panel show the OK alarm status. For details about each indicator, see "2.2 Names and Functions of the Individual Parts P.15". Information Displayed on MCL View By installing MCL View on the local PC, you can view various information regarding the module Alarm Function For details about the alarm setting for the temperature channels, see "4.6.2 Alarm Settings P.29". OK (Abnormal Input) Alarm If the input signal level of the transducer becomes abnormal, the OK alarm is output. Even when the input signal level returns to normal, the OK alarm is retained for approximately another 15 seconds by the off-delay timer. DANGER Alarm DANGER Alarm is output when any one of the measurement values exceeds the DANGER setting value. ALERT Alarm ALRET Alarm is output when any one of the measurement values exceeds the ALERT setting value. First-out Indication From among the channels for which the first-out indication function is enabled, you can identify the one to which the alarm (DANGER, ALERT) is output the earliest. For details about the first-out indication function, see "4.6 Temperature Channel Settings P.27". 12

15 Chapter 2 Overview of Temperature Monitor Module Alarm Delay You can set the delay time (from 0.0 to 99.0 seconds) for each channel to prevent DANGER Alarm or ALERT Alarm from being output by mistake due to noise or other reasons. For details about the alarm delay time setting, see "4.6.2 Alarm Settings P.29". Alarm Logic Alarms for several channels can be output via AND or OR. For details about the logic setting, see "4.7 Relay Setting P.31". Alarm Relay Mode Either NORMALLY DE-ENERGIZED or NORMALLY ENERGIZED can be selected by the relay. For details about the alarm relay mode setting, see "4.7 Relay Setting P.31". The use of NORMALLY ENERGIZED (non-energized alarm) is recommended for the alarm relay mode. The use of NORMALLY DE-ENERGIZED (energized alarm) may prevent the relay from being energized when internal power supply is in an abnormal state. Alarm Reset Methods From the following methods, select how the alarm should be handled when the input signal returns to normal: Auto-reset: The alarm status is cancelled automatically. Self-hold: The alarm status is retained until a short-circuit between RES1 and RES2 terminals on the instrument rack, or until the alarm reset operation on VM-771B MCL View, or until alarm reset operation using Modbus communication (optional). For details about the alarm reset options for the temperature channel, see "4.6.2 Alarm Settings P.29". For details about the reset options for alarm relay, see "4.7 Relay Setting P.31". First Low Alarm Bypass Function When this function is enabled, only the alarm display is activated if the first alarm detected after power-on is the Low alarm, in which case contact output is suppressed until the measurement value exceeds the value specified for the Low alarm. This function is useful for suppressing Low alarm output in cold machine prior to startup Output Function Timed-OK Channel Defeat By enabling this function, DANGER Alarm, ALERT Alarm, indication values and recorder outputs can be shut off when the OK alarm is output. For details about how to set timed-ok channel defeat, see the basic settings described in "4.6 Temperature Channel Settings P.27". Recorder Output The analog signals (voltage signals or current signals) proportional to the temperature are output from the recorder output connector on the instrument rack. For details about the recorder output setting, see "4.6 Temperature Channel Settings P.27". Contact Output Contact signals output from the relay are output from the contact output terminal block on the instrument rack. 13
