QUENCH
Temperature Time Speed
This opcode is used to start a quench cycle. The quench cycle is independent of any program that is
running. A new recipe can be started while the quench timer is active.
The Temperature is the quench temperature controller set point. The quench temperature controller must
be defined as a slave instrument in the Slave Instrument Setup menu and configured in the Furnace Setup
menu as Instrument # 4 . The range is -301 (disable) – 30000.
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. Once the quench
timer has timed out, the quench speed changes to an idle speed, and the end of quench cycle event pulses
on and off.
The Time is the quench time in minutes. The range is -1 (disable) – 9999.
The Speed is used to trigger an Event (#6, by default, which can be changed in the Furnace Setup menu).
While this quench cycle is active, there are three events that can be triggered:
• Quench speed event (Default: #6)
• Quench run event (Default: #0)
• End of quench event (Default: #7)
All of these events must be configured in the Furnace Setup menu.
Quench Speed Event
While the quench timer is active, if a high speed was selected, the quench speed event will be on. This Event
can control the agitator speed, high or low. This Event will remain off if the quench speed is set to low.
Quench Run Event
While the quench timer is active, the Quench Run Event is on.
End of Quench Event
When the End of Quench Alarm is activated at the end of the quench cycle, the user must acknowledge the
alarm. While the End of Quench Alarm is active, the End of Quench Event will be on.
RAMP
Temperature Setpoint Atmosphere Setpoint Time
This opcode changes the temperature set point linearly over time.
The Temperature Setpoint is the setpoint to send for the temperature process variable. The range is -301
(disable) to 30000.
The Atmosphere setpoint is the setpoint to send for the atmosphere process variable. The range is -0.01 to
99.99.
The Time is the total time for the program to reach the desired setpoint(s), in Hours:Minutes format. The
Hours range from 0 – 166, and the Minutes range from 0 – 59.
The band limit can be changed by the SET_WAIT opcode.
RAMPR
Temperature Setpoint Option Decimal Rate
This opcode changes the temperature set point at a rate of degrees per minute.
The Temperature Setpoint is the setpoint to send for the temperature process variable. The range is -301
(disable) – 30000.
The Option Decimal will alter the decimal point in the rate. The range is -1 (disable) – 2.
