1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, snap-in brackets provided.
INSTALLATION PRECAUTIONS
- The thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in)
- Ensure that the working conditions are within the limits stated in the TECHNICAL
SPECIFICATIONS section.
- Do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations
or shocks.
- In compliance with safety regulations, the device must be installed properly to ensure
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.
2 ELECTRICAL CONNECTION
Important
- Use cables of an adequate wire gauge for the current running through them.
- To reduce any electromagnetic interference connect the power cables as far away
as possible from the signal cables.
-
Power supply for TC3B23N5V: 115 VAC.
- Power supply for TC3B23N7V: 230 VAC.
PRECAUTIONS FOR ELECTRICAL CONNECTION
- If you use an electrical or pneumatic screwdriver, adjust the torque to a maximum of
0.5 N•m (4 in. lb).
- If the device was moved from a cold to a warm place, the humidity may have caused
condensation to form inside. Wait about an hour before switching on the power.
- Make sure that the supply voltage, electrical frequency and power are within the set
limits. See the section TECHNICAL SPECIFICATIONS.
- Disconnect the power supply before doing any type of maintenance.
- Do not use the device as safety device.
- For repairs and for further information, contact the PENN sales network.
3 FIRST-TIME
1. Install following the instructions given in the section MEASUREMENTS AND INSTALLA-
TION.
2. Power up the device as shown in the section ELECTRICAL CONNECTION and an internal
test will be run.
The test normally takes a few seconds, when it is finished the display will switch off.
3. Configure the device as shown in Table 6.1 in the section SETTINGS.
Recommended configuration parameters for first-time use.
PAR. DEF. PARAMETER MIN... MAX.
SP 0.0 setpoint r1... r2
P2 0 temperature unit of measurement 0 = °C 1 = °F
d1 0 defrost type 0 = electric 1 = hot gas
2 = compressor stopped
Then check that the remaining settings are appropriate; see the section CONFIGURA-
TION PARAMETERS.
4. Disconnect the device from the mains.
5. Make the electrical connection as shown in the section ELECTRICAL CONNECTION with-
out powering up the device.
6. Power up the device.
4 USER INTERFACE AND MAIN FUNCTIONS
4.1 Switching the device on/off
1. If POF = 1, touch the ON/STAND-BY key for 4 s.
If the device is switched on, the display will show the P5 value ("cabinet temperature" default);
if the display shows an alarm code, see the section ALARMS.
