Note 6
.
MUAL
, mute alarm-relay option, determines whether the user can cancel
the relay action by pressing the RUN key when a relay is activated by
temperature alarms. This setting only applies to Relay Mode
ALAM
and
ALBE
.
And this parameter setting only affects the relay action, not the on-board buzzer.
In situations where the on-board buzzer is triggered by temperature alarms, i.e.,
one of the relay’s
rL
is set to ALBE, pressing down the RUN key will always mute
the on-board buzzer.

INIT
, initialization, allows all parameters to be reset back to factory
default values if the user select
INIT
= Y.

On-board Buzzer Sound
The on-board buzzer will give different sound at different program events. The
table below listed different sounds and the corresponding events. The program-
related sound cannot be muted. When the buzzer is triggered by temperature
alarms, the user can use the RUN key to temporarily mute the on-board buzzer.
The alarm buzzer will be re-activated once the temperature moves out from the
alarm-zone.
Table 19. Buzzer sound.

Event
One short beep
Start of a program
Pause/resume a step-timer
Three short beeps
Temperature reaches the timer-start-
point, i.e., a step-timer starts counting
down time.
Two long beeps
A step-timer is reached, i.e., the end of
a step.
Four long beeps
A program is ended or stopped.
Long beeps, continuously
Temperature alarm is triggered (only
applies to situations where Relay Mode,
RL1 or RL2, is set to ALBE.
9.
Sensor Error
If there is no sensor connected or the sensor input signal is out of range, the
controller will show Out of Range Alarm on the top window, i.e., flash “
ORAL
” and
932°F (or 500°C) in the top window. When the controller detects sensor error, it
will stop all outputs and pause the program if a program is running. The program
will be resumed if the sensor error is removed.

Application and Wiring Examples
10.1.
Using DSPR320 for low-oxygen brewing in a BIAB setup.
In this example, a DSPR320 is used to control the heater in a BIAB kettle. The
Relay 1 will be used to control the wort-circulation pump during mashing, and the
Relay 2 will be used to control a smaller pump for circulating cold water through
an immersion chiller to cool the wort. The program we used in this example is
fictional but based on a real recipe.
In the Main Menu, go to
mPRG
and enter the MASH program.
