Distilling Controller, DSPR400
Version 1.3 (Sep, 2021)
Caution
•
This controller is intended to control equipment under normal operating
conditions. Failure or malfunction of the controller may lead to abnormal
operating conditions, which result in personal injury or damage to the
equipment or other property. Devices (limit or safety controls) or systems
(alarm or supervisory) intended to warn of or protect against failure or
malfunction of the controller must be incorporated into and maintained as part
of the control system.
•
Installing the rubber gasket supplied will protect the controller front panel from
dust and water splash (IP54 rating). Additional protection is needed for higher
IP rating.
•
This controller carries a 90-day warranty. This warranty is limited to the
controller only.

Figure 1. The front panel of DSPR400
1). Top display.
This display indicates the temperature sensor read out value.
When timer is activated, it will show time and temperature alternately.
2). Bottom display.
In distilling mode, this display will show the percentage of
power being sent to the external SSR after the initial heat up phase. In mashing
control mode, this display will show the set temperature.
3). Temperature setting adjusting indicator.
This is the small dot at the lower
right corner. In mashing mode, when temperature set point is adjusted, it will
start to flash. It reminds you that you need to press the knob to confirm the
change. Otherwise, the temperature setting will return back in 2 seconds after
you stop the adjustment.
4). AL1 indicator
. This red LED indicates the status of Relay 1 (AL1). When it
is on, the relay is closed; when it is off, the relay is open.
5). AL2 indicator
. This red LED indicates the status of Relay 2 (AL2). When it
is on, the relay is closed; when it is off, the relay is open.
6). Mashing mode indicator (MASH).
This yellow LED light indicates the
operation mode of the controller. When it is on, controller is in mashing mode;
when it is off, controller is in distilling mode.
7). Output indicator (OUT).
This green LED light is synchronized with output. It
shows how much power the regulator is sending out (as a 12VDC control signal
pulse through terminal 6 and 7). When it is on solid, the output is 100% on. When
it is off, there should be no output. When it is flashing, the frequency of the
flashing is an indication of high or low power output. Higher frequency means
higher power output.
8). Rotary switch (knob).
Turn it clockwise to increase the output power (or
selected parameter value); turn it counter-clockwise to reduce the output power
(or selected parameter value). Press it briefly to reset the timer (if enabled) and
to switch between mashing and distilling mode. Press and hold it for 5 seconds
to enter parameter settings menu. Please see section 6 for details.
9). Function key A & B.
There are two Function Keys named “A” and “B” can
be used to reset/cancel relays. “A” is for Relay 1, Key “B” is for Relay 2
. Please
check note 20.

Figure 2. Terminal assignments of DSPR400.
3.1 Sensor connection
DSPR400 only accepts Pt100 RTD temperature sensor. For a three-wire RTD
with standard DIN color code, the two red wires should be connected to the
terminals 3 and 4. The white wire should be connected to terminal 5. For a two-
wire RTD, the wires should be connected to terminals 4 and 5. Jump a wire
between terminals 3 and 4.
3.2 Power to the controller
The power cables should be connected to terminals 9 and 10. Polarity does not
matter. It can be powered by 85-260V AC power source. Neither a transformer
nor jumper is needed to wire it up. For the consistent with the wiring example
described later, we suggest you connect the hot wire to terminal 10 and neutral
to 9.
