Application

Indication of the status of e-stop buttons in an e-stop chain. We recommend

to use the BH 5922 together with DOLD E-stop modules (approval).

Function

If all the e-stop buttons are closed all green LEDs are on. If one button is

activated the corresponding LED goes off.

The e-stop buttons are connected in series, therefore only one LED goes

off even if several buttons are pressed. Only the first activated button in

the row is indicated. When this e-stop button is released again the LED

lights up again and the LED of the next activated button in the row goes

off.

If the variant B_ 5922/0_2, B_ 5922/0_4, B_ 5922/0_5 is connected to a

IP 5503 in Plug and Play modus the outputs show the state of the E-stop

buttons an dthe LEDs the state of the status LEDs Ι1 - Ι8 on the e-stop

monitor.

Indicators

Notes

When using B_ 5922/00_ or B_ 5922/01_ for single channel monitoring or

2-channel connection of the e-stop chain the e-stop monitor has to be

conected to the loop between S11 and S12 of the e-stop module. In this way

channel AB is monitored.

In a 2-channel e-stop loop, the e-stop monitor has to be connected to the

channel which normally is between the terminals S11 and S12 of the e-stop

module. The E-stop monitor and the e-stop module have to be connected to

the same DC 24 V power supply. When using an E-stop module with AC-

supply the minus-terminal of the e-stop monitor (A2) must be connected to

the minus-terminal of the e-stop control voltage (S21 or PE) on the e-stop

module.

Setup procedure

CANopen mode

With switch position "CANopen" the CANopen protocol is active on the

interface. The configuration of the device is made by software, e.g. Pro

CANopen. The configuration file for BH 5922 can be ordered with

reference: PN5501/CD/01/000

Plug and Play mode

With switch position "Plug and Play" a variant of the CANopen protocol

is active on the interface. The unit setting is done with a switch on the

front, see picture below. If a system is on plug and play mode it can be

switched over to CANopen protocol at any time.

Address setting Plug and Play mode

To allow the E-stop monitor to communicate with a corresponding device

via the CAN-bus the addresses have to be set with the 2 rotational

switches on the front according to the table below. Adresses between

1...49, 51...99 are possible. Adress 0 and 50 cannot be chosen in Plug

and Play mode.

Setup procedure

Notes for Plug and Play mode

On the BL-models with 2-channel monitoring of the e-stop loop 2

addressees and 2 transmission rates can be chosen (channel AB and

channel CD). For correct operation the adress settings must be different

and the transmisson rate settings must be the same.

The screen of the bus wire has to be connected to A2 of the e-stop

monitor.

Setup procedure

1.) Connect CAN-bus to terminals CAN_L and CAN_H

2.) Terminate the physical end of the bus by connecting a termination

resistor of 120 Ω between CAN_L and CAN_H on the first and last

module of the bus

3.) Connect screen of bus wire to A2

4.) Select transmission rate (e.g. 20 K bit/sec) using the rotational switch

on the front (see drawing)

5.) Select address of the module using rotational switches on the front

(see drawing and above example)

Attention:

To communicate in a system configured in Plug and Play

modus it is necessary to set one module in the system to

the address 1.
