Troubleshooting And Error Messages - BriskHeat X2 Manuel D'instructions

When the TUNE or TUNE AT SETPOINT program is complete the PID values are updated
automatically. The process temperature will rise to setpoint and control should be stable. If not, this
may be because optimum cycle time is not automatically implemented. To set the cycle time see
PROPORTIONAL CYCLE-TIME.
PROPORTIONAL CYCLE-TIME
The choice of cycle-time is influenced by the external switching device or load. e.g. Contactor or
SSR. A setting that is too long for a process will cause oscillation or a setting that is too short will
cause unnecessary wear to an electro-mechanical switching device.
Factory set - To use the 20 sec factory set cycle-time no action is needed whether autotune is
used or not.
To Manually Select AUTOTUNE Calculated CYCLE-TIME
When AUTOTUNE is completed, enter program (▲ ▼) and select CYC.t in Level 1. The display
will read CYC.t:20 (factory setting)
To view the new calculated optimum value, press and hold both Þ and ▼ buttons until indexing
stops. The calculated value will be displayed e.g. A16. If acceptable, exit program (▲ ▼) to
implement this setting.
To Pre-select Automatic Acceptance of AUTOTUNE Calculated CYCLE-TIME
Before AUTOTUNE is initiated select CYC.t in Level 1, press and hold both Þ and ▼ buttons until
indexing stops at A – –. Exit program (▲ ▼) to accept calculated value automatically.
To Manually Pre-select Preferred CYCLE-TIME
Before AUTOTUNE is initiated select CYC.t in Level 1, press and hold both Þ and ▲ or ▼ buttons
until indexing stops at preferred value then exit program (▲ ▼) to accept.

ACTION
Make sure plug is securely connected
Turn switch to on position
Replace fuse
Increase the setpoint value
Review operating procedures and reset
parameters
Replace fuse
Make sure plug is securely connected
Check resistance reading
Contact factory for target reading and
assistance
ACTION
Check sensor/wiring
De-power briefly
Replace unit if problem persists
Select proportional mode
1. If display setpoint=0 then enter setpoint
2. If SP1 set to ON/OFF in CyC.t then select
proportional mode
3. Change conditions. e.g. raise setpoint
4. Try tunE : At.SP
5. If the error message persists, contact
