PNOZ e1p Introduction Validity of documentation This documentation is valid for the product PNOZ e1p. It is valid until new documentation is published. This operating manual explains the function and operation, describes the installation and provides guidelines on how to connect the product.
This gives advice on applications and provides information on special fea- tures. Safety Intended use The safety relay PNOZ e1p provides a safety-related interruption of a safety circuit. The safety relay meets the requirements of EN 60947-5-1 and EN 60204-1 and may be used in applications with: E-STOP pushbuttons...
Disposal In safety-related applications, please comply with the mission time T in the safety-related characteristic data. When decommissioning, please comply with local regulations regarding the disposal of electronic devices (e.g. Electrical and Electronic Equipment Act). Operating Manual PNOZ e1p 21242-EN-13...
The safety device remains effective in the case of a component failure. The safety outputs are tested periodically using an off-test. Block diagram/terminal configuration Input Input Start Power Test Diag- Pulse nostic Output S11 S21 Operating Manual PNOZ e1p 21242-EN-13...
The unit checks whether the input circuit is opened and then closed when supply voltage is applied. Increase in the number of available contacts by connecting contact expandsion modules or external contactors/relays. Operating Manual PNOZ e1p 21242-EN-13...
When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket or end angle). NOTICE If you are connecting several units logically, please note the guidelines in the section entitled Logic connection between several units [ 14]. Operating Manual PNOZ e1p | 10 21242-EN-13...

PNOZ e1p Logic connection between several units From Version 3.0, safety outputs on the PNOZ e1p can be logically linked to the safety in- puts on other PNOZelog units. Units from the PNOZelog product range can be logically connected to each other and to units from the PNOZmulti product range.
Status indicators POWER Supply voltage is present, operating mode is detected. POWER Initialisation phase CH.1 There is a high signal at safety output 14. CH.2 There is a high signal at safety output 24. Operating Manual PNOZ e1p | 15 21242-EN-13...
The number of LED flashes corresponds to a digit in the error code. The error code can consist of up to 4 digits. The digits are separated by a longer period without flash- ing. The entire sequence is constantly repeated. INFORMATION Error code 0: 16 flashes Operating Manual PNOZ e1p | 16 21242-EN-13...
