5. Important information
!
WARNUNG
Dangerous electric voltage!
May cause electric shock and burns.
Before beginning work, disconnect system and device.
Correct and safe operations of any device requires that it has been transported and stored appropriately, installed and commissioned correctly and is being operated according to the instructions.
Only persons familiar with installation, start-up and operations and possessing qualifications appropriate for their work may perform work on the device. They must observe the contents of the operating instructions, the information printed on the device and the relevant safety regulations for construction and operation of electric installations.
The devices are manufactured in accordance with DIN / EN and leave the production site in a condition of safety-related flawlessness.
If in any case the information provided in the operating instructions should be insufficient, please contact us directly, or address your local representative.
When using the device outside the area of applicability of the industrial norms referred to in the present operating instructions and valid in Europe, in their stead comply with the applicable regulations valid in the country of application.
!
Caution!
Do not connect or disconnect the device under power. Before connecting the device to the mains, make sure that the control voltage according to the type plate (on the side of the device) U
C
matches the voltage of the grid which the device is to be connected to!
Caution!
!
If the «operating current» function is programmed for all relays, a failure of control voltage or of the system may remain undetected. When using the device for control, it is the operator's responsibility to detect this error by regular controls. We recommend to program at least one relay in the system for standby current and to evaluate it accordingly.
Caution! Multi-voltage power supply
The device is equipped with a multi-voltage power supply suitable for DC and AC power supply. Before connecting the device to the mains, make sure that the permissible control voltage range according to the type plate (on the side of the device) U
C
matches the voltage of the grid which the device is to be connected to! datum / name ) : 13.05.2011 Sc

6. Installation
The device can be fastened:
Distributor installation or switching cabinet on 35 mm mounting rail according to EN
60715
Wall-mounting with M4 screws. (additional bar not included in delivery)
Connect in accordance with connection diagram or type plate.
Pay attention to the maximally permissible temperature when installing into a switching cabinet. Provide sufficient distance from other devices or heat sources. If cooling is hampered e. g. by close vicinity of devices with increased surface temperature or by obstruction of the cooling air flow, the permissible ambient temperature is reduced.
7. Detailed description
The WR250 displays and evaluates the temperatures transmitted from the wireless sensors WS Pt 100.
The hottest wireless sensor switches the relay.
For the relays K1 (alarm 1), K2 (alarm 2) and K3 (alarm 3), the following can be selected individually: o alarm value o hysteresis o response and reset delay o operation current or standby current o cyclic relay test (e. g. K1 for ventilator) o alarm in case of error 3 (no radio contact with WS Pt 100)
In case of an error at the WS Pt 100 wireless sensor, the relay will switch off the sensor alarm (K4), and the red LED is lit.
In addition, the MIN and MAX temperature values of each WS Pt 100 wireless sensor are stored.
The device can be polled remotely via a RS485 Modbus interface, and data can be queried.
Under difficult radio reception conditions or unfavorable mounting positions (e.g. shielded switchgear-cabinet) an external antenna can be connected.

8.16 Device reaction time – measuring time t
M
The reaction time of the device depends on the measuring and transmission times of the wireless sensors (see operating instructions WS Pt 100 wireless sensor).
The wireless sensors measure the temperature every 1 s, 10 s or 100 s and transmit it to the WR250 after every single, after every 10 th
or after every 100 th
measurement.
Consequently, there may be delays in sending and evaluating temperature changes.
Temperature changes > 4 °C will be sent immediately after measurement.
The delay times 8 dal .

11. Troubleshooting
8 Err1 8 or 8 Err2 8 shown in the display cause remedy sensor short-circuited or sensor interrupted at the WS Pt 100 wireless sensor please check temperature sensor at the WS Pt 100 wireless sensor for being electrically in order and correctly connected.
(see operating instructions: WS Pt 100 wireless sensor)
8 Err3 8 shown in the display cause remedy no radio contact with the WS Pt 100 wireless sensor
distance from WS Pt 100 wireless sensor too great
storage capacitor in the WS Pt 100 wireless sensor exhaustively discharged
reduce distance between devices
charge storage capacitor, illuminate WS Pt 100 wireless sensor with > 1000 lux for approx. 2 – 3 hours
8 Err4 8 shown in the display cause illumination of the WS Pt 100 wireless sensor too low or failed remedy provide illumination or increase light intensity, respectively
8 Err5 8 shown in the display cause energy level of the WS Pt 100 wireless sensor too low remedy charge storage capacitor, illuminate WS Pt 100 wireless sensor with > 1000 lux for approx. 2
– 3 hours
8 Err8 8 shown in the display cause WR250 internal error remedy send the device in for examination

Device refuses programming cause Code lock remedy
The code lock provides protection from unauthorized manipulations of the device. When code lock is activated, parameters cannot be changed. The pin can be selected by the user. pin code unknown? → perform code reset:
Upon activation of the control voltage, keep «Set» key pressed for 2 s
display changes to 8 8888 8 – 8 Cod 8 – 8 off 8 – 8 8888 8
release «Set» key
code lock is deactivated, pin code is «504»
No registration of a WS Pt 100 wireless sensor with the WR250 possible cause
distance between wireless sensor and WR250 too great
wireless sensor power too low for work
wrong registration contacts linked at the wireless sensor or static linkage of remedy the contact
reduce distance between the devices
charge storage capacitor, illuminate WS Pt 100 wireless sensor with > 1000 lux for approx. 2 – 3 hours
link registration contacts at the wireless sensor only briefly (see operating instructions: WS Pt 100 wireless sensor)
