Example: if customer requires a Deviation Value of ±10 degrees around a setpoint (using Output 2 as alarm) Output 2: disabled (this enables the Alarm 2) Alarm 2: - Deviation Contact Closure type: Deviation---Band AL2 High: 10 (Band they want around Setpoint 2) Then the Band Value is to be entered under AL2 HI: 10 not 80+10 = 90 28 ALARM ENABLE/DISABLE AT POWER ON: Press d 15) Display flashes previous selection. Press b to ENBL enable or DSBL disable. Press d 16) Display shows STRD stored message momentarily and then advances to ALR.L only, if it was changed, otherwise press a to advance to the ALR.L Alarm 1 Low Value Submenu. If the alarm is enabled at Power On, the alarm will be active right after reset. If the alarm is disabled at Power On, the alarm will become enabled when the process value enters the non alarm area. The alarm is not active while the process value is approaching Setpoint 1. ALARM 1 LOW VALUE SUBMENU: Press d 17) Display flashes 1st digit of previous value. Use b and c to enter new value. Press b & c 18) Use b and c to enter Alarm 1 Low Value. Press d 19) Display shows STRD storage message momentarily and then advances to ALR.H only, if it was changed, otherwise press a to advance to ALR.H Alarm 1 HI Value Submenu. ALARM 1 HI VALUE SUBMENU: Press d 20) Display flashes 1st digit of previous value. Use b and c to enter new value. Press b & c 21) Use b and c to enter Alarm1 HI Value. Press d 22) Display shows STRD stored message momentarily and then advances to the next menu only, if it was changed, otherwise press a to advance to the next menu. If the input wires of the meter get disconnected or broken, it will display + OL Input (+) Overload message. For safety purposes you can set up your alarm to be triggered when input is open. 29 3.2.8 Analog Output (Retransmission) Menu Analog Output can be configured as Retransmission or Control outputs. In this section we will discuss Retransmission Output. This unit is equipped with two physical outputs that can only be configured as follows: Alarm 1 & Alarm 2, Alarm 1 & Output 2, Output 1 & Alarm 2, Output 1 & Output 2, Analog Out 1 & Alarm 2, Analog Out 1 & Output 2. Analog Output is available only if Analog Output Option board is factory installed. If Analog Output Option is not installed, the instrument will skip to Alarm 2 Menu. Figure 3.6 Flow Chart for Analog Output (Retransmission) Menu ENTER ANALOG OUTPUT MENU: Press a 1) Press a, if necessary, until CNFG prompt appears. Press d 2) Display advances to INPT Input Menu. Press a 3) Press a, if necessary, until display advances to ANLG Analog Output Menu. Press d 4) Display advances to Analog Output ENBL Enable or DSBL Disable Submenu and flashes the previous selection. 30 ANALOG OUTPUT ENABLE/DISABLE SUBMENU: Press b 5) Scroll though the available selection until ENBL displays to use Analog Output Retransmission (output proportional to the input signal). Press d 6) Display shows STRD stored message momentarily and then advances to CURR or VoLT Submenu only if it was changed, otherwise press a to advance to CURR or VoLT Current/Voltage Submenu. If DSBL Analog Output Disabled was selected, all submenus of Analog Output Menu will be skipped and the meter will advance to ALR2 Alarm 2 Menu. If ENBL Analog Output Enabled was selected, Output 1 would be automatically Disabled, and reassigned as Analog Output. CURRENT/VOLTAGE SUBMENU: Press d 7) Display flashes CURR Current or VoLT Voltage. Press b 8) Scroll through the available selection: Current or Voltage (Example VoLT ). Press d 9) Display shows STRD stored message momentarily and then advances to RD1 Submenu only if it was changed, otherwise press a to advance to RD1 Reading 1 Submenu. READING 1: Press d 10) Display flashes 1st digit of previous “Reading 1” value. Press b & c 11) Enter “Reading 1” value. (Example 0000) Press d 12) Display advances to OUT.1 Out 1 Submenu. OUT 1: Press d 13) Display flashes 1st digit of previous “Out 1” value. Press b & c 14) Enter “Out 1” value. (Example 00.00) Press d 15) Display advances to RD!2 Reading 2 Submenu. READING 2: Press d 16) Display flashes 1st digit of previous “Reading 2” value. Press b & c 17) Enter “Reading 2” value. (Example 9999) Press d 18) Display advances to OUT.2 Out 2 Submenu. OUT 2: Press d 19) Display flashes 1stt digit of previous “Out 2” value. Press b & c 20) Enter “Out 2” value. (Example 10.00) Press d 21) Display advances to the ALR2 Alarm 2 Menu. The above example is for 0 - 10 V of the entire range of the Process Input and Analog Output. For 0 - 20 mA output you need to set “Analog Type” to Current and OUT 2 to 20.00. 31 Accuracy of Analog Output board is +/-1% of FS (Full Scale) when following conditions are satisfied: 1. The input is not scaled below 1% of Input FS (10 mV @ 1 V or 0.2 mA @ 20 mA input ranges). 2. Analog Output is not scaled below 3% of Output FS (300 mV @ 10 V or 0.6 mA @ 20 mA output ranges). Otherwise certain corrections need to be applied. For example: For...
