8. Special remarks
8.1 Installation
Thyro-S requires a vertical fitting position. With cabinet mounting suf-
ficient ventilation of the cabinet must be ensured. The distance bet-
ween the Power Controller and the cabinet ceiling or other mountings
should be at least 150 mm. The distance below the Power Controller
should be at least 100 mm. The devices may be installed next to each
other without lateral distance. Heating up of the device by heat sour-
ces must be avoided. The dissipation of the Power Controller is stated
in the Type overview table.
ATTENTION
Grounding must be carried out according to local elec-
tricity board regulations! (grounding screw for protective
conductor connection on fastening adapter is provided).
The grounding also serves EMV devices (Y capacitor
4.7 nF).
For Thyro-S with type currents up to 60A, adapters can be delivered
for the 35 mm top-hat rail assembly.
8.2 Commissioning
The device must be connected to the mains and the associated load
according to the corresponding connecting plans.
On delivery the device is parameterized and adjusted to the respec-
tive power section. If a different operating mode is desired, then it
must be set with DIP fix 1 and 2 by the user (commissioning phase).
ATTENTION
Heat sinks and neighbouring plastic parts can become hot
during operation
8.3 Service
The devices delivered have been produced under quality standard
ISO 9001.
Should nevertheless faults or problems occur, our 24-hour service
hotline: Phone 02902 / 763-100 is at your service.

8.4 Checklist
• LED ON lights up green -> mains voltage or supply voltage is
available
• LED ON not lights up green
· Check fusing of the power unit (built in semi-conductor fuse F1).
If the fuse is defective check load and wiring to load.
· Check synchronisation voltage on X1.1
· Check external back-up fuse
· Check control fuse (F2) 500V 1.6A
· With Thyro-S ...H RL 1 check 24V (AC/DC) power supply where
applicable
• Supply available but no load current
· Check mains voltage
· Switching on signal (digital set point, X22.1 versus X22.3 ≥ 3)
· Check load circuit for interruptions
· Check flashing LED signals (chapter 3.3)
• Load current does not have the expected value
· Check switching on signal (digital set point) for continuous signal
ON.
With optional bus module:
· Check bus switching on signal (bus set point) for continuous signal
ON.
. Check all parallel load resistances for current flow.
• Load current is flowing without triggering
· Check the wiring of the power unit (in case of first activating).
In very rare cases a thyristor short circuit may have occurred.
