POWER UP PROCEDURE Verify all electrical connections have been properly made before applying power to the instrument. If the instrument is being powered for the first time, it may be desirable to disconnect the controller output connections. The instrument will be into control following the power up sequence and the output(s) may turn on. During Power up, a self-test procedure is initiated during which all LED segments in the two front panel displays appear and all LED indicators are on.
DOWN Key Decrements displayed parameter value/cycles through options. PROF Key Cycles through Program (profile) numbers. RUN/HOLD Key Runs, holds or aborts current program (profile). Jumps to next segment, when program is running. Selects/de-selects Manual Control. Sets a segment to Dwell when defining a program.
INDICATORS Control Status Indicators AT - On when Self-Tune is active; flashes when PreTune is active. ALM - Flashes when any alarm is active. OP1 - On when primary control output is active. OP2 - On when secondary control output (if fitted) is active. MAN - On when Manual Control is selected.
Mode Indicators SET - On when Profile Set Mode is entered; flashes when viewing parameters in Configuration Mode after entry from Base Mode. PRG - On when Profile Set Mode is entered.
Single Setpoint/Base Mode Control With the Setpoint Programmer in Base Mode (i.e. with the RUN, HLD, SET, and PRG indicators off), the two main displays will show the process variable value (upper display) and the setpoint value (lower display - Read Only). To change the setpoint value: 1. Press the SCROLL key until the Message Area displays Setpoint. 2. If Setpoint has been enabled in the Enable Mode, the UP and DOWN keys may be used to change the setpoint value (in the lower display) as required. 3.
indicator will go on continuously. When the operator removes the manual Hold (by pressing the RUN/HOLD key again), the HLD indicator will either flash (indicating that the Deviation-Hold conditions still prevail) or go off (indicating that the Deviation-Hold conditions no longer prevail). RUN INDICATOR FLASHING: This indicates that the program is in a Delay state (i.e. is timed to start after a user-defined delay has elapsed).
MIC 1462 PROFILE PROGRAMMING Programming a profile into the MIC1462 control is broken into three categories: GLOBAL - Those parameters common to all programs. PROGRAM - Those which apply to a specific program as a whole. SEGMENT - Those relevant to a specific segment in a specific program. Global Parameters (common to all programs) (Program Number = A, Segment Number = Blank) 1. Press the mode key until the message display reads “Prof Par”. 2. Press the scroll key once. 3.
STEP DESCRIPTION MESSAGE DISPLAY LockProg FUNCTION AVAILABLE SETTING 5 Program Lock Defines whether the operator is permitted to change program definitions while a program is running/held Defines length of power loss before automatic return to Base Mode after restoration of power, regardless of Recovery Type. On - No changes permitted Off - changes permitted 6 Power Fail Recovery Period Recovery 7 Power Fail Recovery Type Rec Type Defines response to restoration of power after a power loss.
Program Parameters (apply as a whole to a specific program) (Program Number = 1 to 8, Segment = Blank) 1. Press the mode key until the message display reads “Prof Par” 2. Press the scroll key once. 3. Press the Prof key until the desired program # is shown in the program number display. 4. The program parameters will now be displayed in the message display and the setting will be displayed in the lower display. 5. Press the scroll key to go from one program parameter to the next. 6.
STEP DESCRIPTION 7 Start Time** MESSAGE DISPLAY Strt-ti 8 Start Day ** Strtday FUNCTION AVAILABLE SETTING Determines the automatic start time for the profile Determines the day of the week when start time applies 1:00 - 24:59 OFF = manual start only ALL = 7 days a week Mon = Monday tuE = Tuesday Wed = Wednesday thu = Thursday Fri = Friday SAt = Saturday Sun = Sunday 5 dy = Mon - Fri 6 dy = Mon - Sat * Not displayed if deviation hold is off.
Segment Profile Parameters Table STEP DESCRIPTION 1 Final Setpoint Value 3 * MESSAGE DISPLAY Final SP Segment Time or Ramp Rate as selected by Segment Mode parameter in Configuration Mode Time or RampRate Event † Event FUNCTION AVAILABLE SETTING Defines the final value of the setpoint for this segment, selects a dwell segment or indicates a Join, Repeat, or End Program segment Defines the duration/ramp rate of the segment or whether this is a Join, Repeat or End Program segment * Numeric value
Exiting Profile Set Mode The operator may exit from Profile Set Mode by pressing the MODE key. To return to Base Mode, press the MODE key until the Base Mode prompt appears in the Message Display, then press the SCROLL key. SAMPLE PROFILE The Control is capable of storing eight (8) profiles with up to sixteen (16) segments depending on memory. Each segment consists of a final setpoint, time, and event(s) status. The sample profile below is set up to use Profile number 1.
Entering Global Parameters For The Profile Press the mode key until Prof Par is displayed in the Message Display. Press the SCROLL key and Cycles will be displayed with 1 displayed in the Program display. Make changes with the UP and Down arrow keys. Press the SCROLL key to move to the next display. Note: the segment display must be blank. If not, press RUN/HOLD key until the segment display is blank. Description Cycle Count Deviation Hold Time Base Autostart Time Enable Message Display Cycles Dev.
Running The Profile Press the PROF key until 1 is displayed in the Program Display. Press the Run/HOLd key until 1 is displayed in the Segment Display and Final SP is displayed in the message display. Make changes with the UP and Down arrow keys. Press the SCROLL key to move to the next display.
