5.6.3.1. Using the Program Page
After entering the Program Page, press Select to reach the profile you desire to enter/edit.
Press Menu to select the profile. The first parameter displays: Profile #, Segment 1, Ramp
Time. Adjust the value by pressing ▲ or ▼. When the proper value is displayed, press
Menu to continue to the next parameter. Continue using the Menu to view and adjust each
parameter.
If the current segment’s ramp time value is left at 0:00, the next press of Menu advances
to the High Limit Setpoint parameter for that profile (Hi-Lim SP). Continue
entering/verifying all parameters until arriving at the last parameter: Guaranteed Soak
Band (Guar Band). After properly entering all parameters, press Page to return to the top
of the Profile Page. Press Select to enter/edit another profile, press Page to access another
page, or press and hold Page to exit Setup mode.
O
While editing any profile, press Select to advance the control to
the time value for the next segment, until the last segment has
been reached. This allows faster editing of the profile rather than
pressing Menu to advance past each parameter.
If Link To Pro is set to Standby (Stby) in the Program Page at the end of running a Profile,
1. Cycle Complete LED indication goes ON.
2. Controller beeps if End of Cycle beep is enabled.
3. Heater/control output keeps controlling oven temperature at last Soak setpoint.
4. All events programmed (if relay cards are installed and programmed as an event) for
the last Soak Segment stays active.
O
Run a profile indefinitely by linking the profile to itself.
5.6.3.2. Programming Optional Relay Outputs
Optional relay outputs must be configured prior to use. If optional relay outputs are
installed, configure them as alarms or events on the Relay Outputs Page (Section 8.1.8)
before using. If configured as event outputs, these relays can be used as time or
temperature events.
Check your schematic for relay use in your oven, but typical uses for optional relays
include:
• Relay 1: Cooling event
