Model 9200 Programmable Dual-loop Controller
SSi Manual SERIES 9200 42 Programmable Dual-loop
The LIMIT opcode immediately following this opcode sets a time limit on the wait.
A BRANCH opcode immediately following this opcode can be used to change the program flow
based on the inquiry results.
QUENCH opcode is used to start a quench cycle. The quench cycle is independent of any program that is
running. The temperature data is the quench temperature controller set point. The atmosphere
data is the quench time in minutes. The option data can be used to control the agitator speed,
high or low, by Event # 6. Event # 6 OFF equals low speed, and Event # 6 ON equals high speed.
The quench temperature controller must be Aux Instrument # 4 . The quench cycle starts when
the opcode is executed. The set point is sent to the quench temperature controller, the timer is
started, and the high-speed event is turned on if it is selected. When the quench timer times out,
the end of quench cycle (event # 7) is turned on for one second and the high speed event is
turned off.
RAMP This opcode changes the temperature set point and/or the atmosphere set point linearly over time.
The option data is the total ramp time in minutes. The temperature data specifies the final set
point for the temperature set point. The atmosphere data specifies the final value for the
atmosphere set point.
RAMPR This opcode changes the temperature set point at a rate of degrees per minute. The option data
is the final temperature set point and rate of degrees per minute.
RESET This opcode is used to clear all stacks and timers and start a program. The temperature data is
interpreted as a program number and the atmosphere data as a program step. The option data is
not used. The RESET is useful in a weekend shut down program to restart the normal operating
program.
SET_AUX The Set Auxiliary Instrument Set point opcode is used with other instruments in the process such
as flow control or belt speed. The temperature data is the set point and the option data is the
instrument number.
SET_FACT This opcode is used to set the CO factor or the H2 factor of the atmosphere controller. If the
atmosphere type for the loop is set to dew point then the H2 factor is set; otherwise the CO factor
is set. The temperature data is not used. The atmosphere data is used as the factor with decimal
places ignored. The option data is wait, wait up, or wait down. This allows the control loop to
recover from the change before continuing the program.
SET_WAIT This opcode sets the band limits for the wait option or inquiry opcodes. The temperature data
specifies the temperature band (i.e. +/- the value) and the atmosphere data specifies the
atmosphere band.
SETPT This opcode is used to set the temperature and/or atmosphere set points. Either or both of the set
points can be specified. The options are None or Wait. If both set points are specified the Wait
applies to both.
SOAK This opcode is an unconditional soak for the time (in hours and minutes) specified in the option
data.
TC_INQ The temperature inquiry is used to wait for the actual control temperature to reach the value
specified in the “temp” field.
The options are:
• wait, reach within band;
