3.2 Structure and function
The safety relay ReLy TIME1 is an electrical switching device with inputs and outputs.
The safety capable inputs of the safety relay are connected to safety sensors or safety
switches.
2 safety capable inputs control the internal relays, which are used to reliably switch the
enabling current paths.
The enabling current paths close only when the two safety capable inputs close within
3s of one another.
At the enabling current paths it is possible to connect, for example, actuators with
positively guided contacts.
Opening the input circuit causes the two enabling current paths to open immediately
and for the release-delayed enabling current path to open after a delay. The delay time
is adjustable.

4 Project planning
4.1 Manufacturer of the machine
The manufacturer of the machinery must carry out a risk assessment and apply appro‐
priate protective measures. Further protective measures may be required in addition to
the product.
The product must not be tampered with or changed, except for the procedures descri‐
bed in this document.
The product must only be repaired by the manufacturer of the product or by someone
authorized by the manufacturer. Improper repair can result in the product not providing
the expected protection.
4.2 Operating entity of the machine
Changes to the electrical integration of the product in the machine controller and
changes to the mechanical mounting of the product necessitate a new risk assess‐
ment. The results of this risk assessment may require the entity operating the machine
to meet the obligations of a manufacturer.
After each change to the configuration, it is necessary to check whether the protective
measure provides the necessary protection. The person making the change is responsi‐
ble for ensuring that the protection measure provides the necessary protection.
The product must not be tampered with or changed, except for the procedures descri‐
bed in this document.
The product must only be repaired by the manufacturer of the product or by someone
authorized by the manufacturer. Improper repair can result in the product not providing
the expected protection.
4.3 Design
Installation site
The safety relay must be installed in a control cabinet with an enclosure rating of IP54
or higher.
The safety relay must be installed on a mounting rail (35mm) in accordance with IEC
60715.
Space requirements in the control cabinet
To ensure sufficient air circulation and cooling, sufficient distance must be kept in the
control cabinet above and below the safety relay.
Sufficient distance must be kept for the connected cables before the module (front
side).

4.4 Electrical integration
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
bEnsure the safety relay is supplied with supply voltage in all operating statuses.
bEnsure that the supply voltage of the safety relay is not connected via safety
sensors or safety switches in order to switch the enabling current paths.
4.4.1 Voltage supply
Prerequisites
•The power supply unit is able to jumper a brief power failure of 20ms as specified
in IEC60204-1.
•The voltage supply and connected signals meet the requirements for SELV/PELV
(EN61140) or NECClass2 (UL1310).

4.4.2 Enabling current paths
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
bEnsure the enabling current paths are supplied by the same voltage supply.
Cross-circuits
Cross-circuits between the enabling current paths or with other signals may not be
detected and can put the machine in a dangerous state.
Measures:
bLay the cables in a protected manner or separately (e.g., within the control cabinet
as per IEC60204-1).
bTake other necessary measures to achieve the required safety-related characteris‐
tic values.
4.4.3 Application diagnostic output
Application diagnostic output Y1
The signal of the Y1 application diagnostic output changes as soon as the enabling
current paths switch. The application diagnostic output is not safe.
Application diagnostic output Y1 is based on the push-pull principle, meaning it can
both absorb and apply current.

Application diagnostic output Y2
Application diagnostic output Y2 outputs the “Reset required” signal with a frequency of
1Hz, e.g. for the connection of a signal lamp.
Application diagnostic output Y2 is based on the push-pull principle, meaning it can
both absorb and apply current.

4.4.4 Restart interlock
Important information
DANGER
Hazard due to unexpected starting of the machine
Death or severe injury
bIf you connect the safety relay to an emergency stop pushbutton, you must use the
restart interlock.
Restart interlock
A reset pushbutton must be connected to allow the restart interlock to be used. The
reset pushbutton must be attached outside of the hazardous area. It must not be
possible to access the reset pushbutton from inside the hazardous area. The entire
hazardous area must be highly visible for all operators from the reset pushbutton.

•"Device connection", page 21
4.4.5 External device monitoring (EDM)
External device monitoring (EDM)
With static external device monitoring, the safety relay tests whether the controlled
actuators (contactors) have dropped out just before energizing the internal relay.
Cross-circuits
Cross-circuits within the external device monitoring (EDM) itself (e.g., before and after
the contactor being monitored) or with other signals may not be detected and can put
the machine in a dangerous state.
Measures:
bLay the cables in a protected manner or separately (e.g., within the control cabinet
as per IEC60204-1).
bTake other necessary measures to achieve the required safety-related characteris‐
tic values.

4.5 Testing plan
The manufacturer of the machine and the operating entity must define all required
thorough checks. The definition must be based on the application conditions and the
risk assessment and must be documented in a traceable manner.
The following tests must be planned:
•A thorough check must be carried out during commissioning and following modifi‐
cations.
•The regular tests of the device must fulfill certain minimum requirements.
4.5.1 Planning the thorough check during commissioning and in certain situations
Overview
Before commissioning the machine and after making changes, you must check whether
the safety functions are fulfilling their planned purpose and whether persons are being
adequately protected.
Minimum requirements
The device and its application must be thoroughly checked in the following situations:
•Before commissioning
•After changes to the configuration or the safety function
•After changes to the mounting or the electrical installation
•After exceptional events, such as after manipulation has been detected, after
modification of the machine, or after replacing components

Subject to change without notice

The thorough check ensures the following:
•All relevant regulations are complied with and the device is effective in all of the
machine’s operating modes.
•The documentation accurately reflects the state/condition of the machine, includ‐
ing the protective device.
The thorough checks must be carried out by qualified safety personnel or specially
qualified and authorized personnel, and must be documented in a traceable manner.
4.5.2 Planning the regular thorough check
Overview
The purpose of regular tests is to identify any defects due to changes or external
influences (e.g. damage or manipulation) and to ensure that the protective measure
provides the necessary protection.
Minimum requirements
The following thorough checks must be carried out at regular intervals:
•Thorough check of the housing for damage
•Thorough check of the cables for damage
•Check the device for signs of misuse or manipulation
•Thorough check of the safety function
The required interval for performing these thorough checks depends on the applicable
safety capability of the overall application, see table 7, page 31.
