M4557 - Model 9210 Nitriding Controller
•ATMOSPHERE, turns ON the atmosphere alarm and turns OFF the temperature alarm
•BOTH, turns ON both the temperature and the atmosphere alarms.
The band limit can be changed by the SET_WAIT opcode.
DOW_INQ This opcode checks the real time clock for the day of the week. This is useful for performing operations on a weekly basis on a specific day. The option data is the day of the week, i.e. SUN, MON, TUE, WED, THU, FRI, and SAT.
EVT_IN This opcode waits for an input event to be turned ON or OFF depending on the option value. The option value is the event number followed by either ON or OFF.
If temperature data and or atmosphere data are specified, they are considered setpoints and will be sent to the appropriate controller.
EVT_OUT The Event Output opcode turns an output ON or OFF event based upon the option value. The option value is the event number followed by either ON or OFF.
If temperature data and or atmosphere data are specified, they are considered setpoints and will be sent to the appropriate controller.
G_SOAK This is a guaranteed soak opcode. The temperature process value must be within the deviation band to allow the soak timer to run. The option value is the soak time in hours and minutes. The band limit can be changed by the SET_WAIT opcode. If Load TC Enable is set to ON, this opcode will wait for all temperature inputs selected to be within the deviation band before starting the soak timer.
GHSOAK This is a guaranteed High soak opcode. The temperature process value must be within the setpoint and the high deviation band range to allow the soak timer to run. The option value is the soak time in hours and minutes. The band limit can be changed by the SET_WAIT opcode. If Load TC Enable is set to ON, this opcode will wait for all temperature inputs selected to be within the acceptable band before starting the soak timer.
GHZSOAK This is a Guaranteed Soak High opcode for a zone. The temperature process value must be above the deviation band to allow the soak timer to run. The option value is the soak time in hours and minutes. The band limit can be changed by the SET_WAIT opcode.
GLSOAK This is a guaranteed Low soak opcode. The temperature process value must be within the setpoint and the low deviation band range to allow the soak timer to run. The option value is the soak time in hours and minutes. The band limit can be changed by the SET_WAIT opcode. If Load TC Enable is set to ON, this opcode will wait for all temperature inputs selected to be within the acceptable band before starting the soak timer.
GLZSOAK This is a Guaranteed Soak Low opcode for a zone. The temperature process value must be below the deviation band to allow the soak timer to run. The option value is the soak time in hours and minutes. The band limit can be changed by the SET_WAIT opcode.
GOSUB The go to subroutine (recipe) opcode is used to call a program and then return to the calling program. This is used to execute standard routines that can be used by many programs. GOSUBs can be stacked up to eight levels. The option data is the program number.
GRAMP This opcode changes the temperature setpoint and/or the atmosphere setpoint linearly over time. The option data is the total ramp time in hours and minutes. The temperature data specifies the final setpoint for the temperature setpoint. The atmosphere data specifies the final value for the atmosphere setpoint. This opcode will cause the setpoint change to wait until all temperature
