Oil cooling (optional)
If the CytroBox is equipped with an additional oil cooling system, it is already
completely assembled ex works.
▶
Ensure that the purity of the cooling water has a maximum particle size of 100 µm.
▶
Make sure that the cooling water supply temperature does not fall below the
dewpoint of the ambient air around the hydraulic power unit.
▶
Observe the following requirements:
– Maximum cooling water input temperature: 15 ... 25 °C
– Minimum cooling water flow: 20 l/min
– Maximum glycol content: 30 %
– Maximum cooling water pressure: < 10 bar
7.5 Electrical interface assignment
▶
For electric installation of the interfaces, proceed according to applicable
regulations for electrical engineering.
▶
You must ensure that the electric power supply is disconnected and also
safeguarded against being switched on unintentionally.
▶
Unintended switching on should be prevented by means of an information sign
indicating that work is carried out at the electrical system.
For operation of the hydraulic power unit, at least the following electrical
connections are required:
1. Supply voltage feed-in 400 ... 500 VAC
2. 20X1: Digital input and output signals
3. 21X1: Safe Torque OFF (STO)
4. 22X1: Multi-Ethernet control communication (network output)
5. 22X2: Multi-Ethernet control communication (network input)
6. 23X2: Cooling unit connection (optional)
7. 23X3: Water valve connection (optional)
8. 30X1: CytroConnect (optional)
9. X26: Engineering port
