Communications

• are executed via PROFIBUS DP at 12 Mbit/s
• For importing the parameter settings from the higher-level controller
• For transferring the diagnostic information to the higher-level controller
• Communications are performed via the ECOFAST X3/X4 connector and can be forwarded from device to device using daisy chaining.

Performance features

• Calculation of output control variables of power output channels
• Setpoints can be adjusted from 0 % to 100 % in increments of 1 %
• Zero cross-switching solid state relay (SSR)
• External fan output for connection of an 230 V AC fan of up to 500 W

Diagnostics

The following faults are detected:

• Heating element fault
• Breakdown of a solid state relay (SSR)
• Incoming fuse has tripped
• Outgoing fuse has tripped or solid state relay (SSR) has high resistance
• Monitoring of the fan output

Air extraction

• To achieve even heat distribution within the enclosure, an internal fan is used. The fan is controlled according to the internal temperature and is also monitored. If the fan is not functioning correctly, a fault is reported to the user.
• The internal fan is available as an accessory and can be replaced if defective.

Supply to main circuit

• The power supply is two-phase with a voltage of 400 V AC (± 10 %).
• The network frequency is 50/60 Hz (± 5 %).

Supply to internal electronics

• The internal electronics of the device must be supplied with 24 V DC ± 20 % (PELV = protective extra low voltage).
• The maximum current consumed per device is 0.25 A.
• Connection of the 24 V DC supply and PROFIBUS DP via the ECOFAST X3/X4 connector
• The 24 V DC supply can be forwarded from device to device using daisy chaining.

Power outputs

• Nine power outputs are available for each device
• Max. 4 000 W switching capacity per output
• Max. 25 200 W switching capacity per device

Fan output

An external 230 V AC fan with a maximum output of 500 W can be operated.

Temperature monitoring

The SIPLUS HCS3200 heating control system is fitted with a sensor for monitoring the internal temperature. When a temperature threshold that is permanently set in the hardware is overshot, all outputs (power outputs and the external fan) are automatically switched off to prevent damage to the device.

Fuses

• Two gG 16 A fuses per power output for protecting the power outputs
• One gG 4 A fuse to protect the fan output
• All fuses are fitted in fuse holders and are easily accessible.
