PCS.smart+ AMS
This device does not have a separate on/off switch. The device
is switched on as soon as it is connected to the mains.
Connect the included supply cable to the device and a suitable
voltage source. Please note the correct voltage and frequency.
The type plate contains any deviating specifications.
We recommend an ELCB for the power and voltage supply.
The ELCB (tripping current 30 mA) must shut off the load
within the prescribed period (200 ms at 115 VAC, 40 ms at 230
VAC). It must be suitable for the maximum load.

DANGER
Electric voltage
Risk of electric shock
a) Always disconnect the unit from the mains before per-
forming work.
b) Secure the equipment from accidental restarting.
c) The unit may only be opened by trained, competent per-
sonnel.
d) Ensure the correct voltages supply.
e) An add-on sensor (Pt100) must be shielded.

The maximum power input of the consumer is 1600 W at a
voltage of 230 V and 800 W at a voltage of 115 V. The max-
imum current is 7 A.
4.4 Signal outputs
The device has various status signals (also see table "Descrip-
tion of signal outputs"). The maximum switching power of
the alarm outputs is 230 VAC/150 V DC, 2 A, 50 VA, each.
An alarm is triggered by the alarm contact / status output (S2)
if the temperature of the cooler is outside the specified limits.
It does not indicate if the alarm was triggered due to excess
temperature or insufficient temperature.
The front film has three LEDs:
Colour Marking Function
Red S2 High/low temperature, device error
Yellow S1 ---
Green OP Normal operation
The LEDs OP and S2 indicate the device status similar to alarm
contact S2.
If the option "temperature signal" is built in, the unit has a
signal output via the analogue output to indicate the actual
cooler temperature.
When the moisture detector (optional) is installed, an alarm
will also be triggered via the alarm contact / status output
(S2) if moisture is still present in the conditioned sample gas
or a cable break is detected.
The temperature signal can be read via the panel plug (S3) us-
ing the M12x1 connector. This plug is located on the terminal
side.
