1 Bul. R Guardmaster Safety Relays () Selection Guide

2 Bulletin R Description The new generation of Guardmaster safety relays addresses the broad scope of applications in the intricate safety world with a range of devices. Designed to meet new functional safety standards, such as EN ISO - and EN, the new family offers key functions to simplify installation and system complexity. A broad range of safety devices such as safety interlock switches, emergency stop devices, pressure sensitive safety mats, and OSSD devices such as safety light curtains are all compatible with the same relay without additional configuration.the functionality of two standard safety relays can be achieved in one Dual Input (DI) device, allowing connection of two dual-channel input devices into one safety relay. A TÜV-approved single rotary switch sets the required function of the safety relay and eliminates the typical redundant switch setting process. Selectable functions include simple logic, reset, timing, and diagnostics. The single-wire safety connection simplifies cascading and expanding safety functions by linking relays with a single-wire connection. A dynamic signal from device to device provides a linkage in accordance with SIL, PLe, allowing easy addition of extra I/O, which can be configured with simple logic combinations. Flexible AND/OR logic can be configured simply in a single relay or through a combination of relays via single-wire connection. The family includes a module designed specifically for guardlocking applications. The GLP uses two proximity sensors to monitor machine motion, and unlocks the gate when safe speed is attained. Expansion modules are available with four immediate or timedelayed outputs. The time delay module can be configured for on delay, off delay, or jog.

6 Bulletin R The logic between the two safety inputs (S, S) and IN (S, S) and the single-wire safety input (L) can be configured to the four options shown below, in either manual monitored or automatic/manual reset configurations (yielding eight settings total). L will only recognize a valid test pattern from the L output of a Guardmaster device. Any other signal to that port will be detected as a fault. (A high signal is considered to be true in this logic. So if an input is to be ignored or muted, OR logic should be used). Note: In case only one safety input is used the second one can be left open if it is configured for OR. An AND conjunction requires this input to be wired to S and S. In case L is not in use, this input needs to be configured for OR. Manual Monitored ( OR IN) OR L ( AND IN) OR L ( OR IN) AND L ( AND IN) AND L Automatic / Manual ( OR IN) OR L ( AND IN) OR L ( OR IN) AND L ( AND IN) AND L IN L AND/ OR = S, S IN = S, S AND/ OR Configuration Setting the Function/ Mode DI, DIS, SI, and CI. Start configuration/overwrite: with power off, turn rotary switch to position and unit is powered up. After power-up test, LED will flash red..

Configuration must be confirmed before operation. A white rectangle on face of device is provided to record unit setting. Enable program mode Set operation mode Cycle power to store Record setting Setting the Time Delay EMD. Start configuration/overwrite: with power off, turn rotary switch RANGE to position and power unit up. After power-up test, LED will flash red.. Set configuration: turn rotary switch to desired position, both RANGE and TIME. LED B indicates position of RANGE and IN of TIME. Note: Position is set when LED is solid green.. Lock in configuration by cycling unit power.. Configuration must be confirmed before operation. A white space on face of device is provided to record unit setting. Note: When in off-delay mode, terminals B and B are used to modify the settings of retriggering. The terminals are not used in on-delay mode. Terminal B is used for the pulse source when the relay is in single pulse jogging mode. OFF-DELAY (RANGE,,, ): Time delay starts when single-wire safety input L changes from HIGH to LOW. Delayed safety outputs remain active until the set time has lapsed. The unit is safe against time extension. Restart the unit by cycling the safety input L, LOW to HIGH. RETRIGGERABLE (JUMPER B-B): In off-delay mode, the device can be set to retriggerable setting. In retrigger mode, if the safety input is triggered and cleared within the duration of the time delay then the timing request is ignored and the safety output contacts will remain closed. Retrigger setting can only be done in off-delay mode and can be set by running a jumper wire from terminal B to B (corresponds with MSR and MSRED delayed outputs). NON-RETRIGGERABLE (NO JUMPER): In off-delay mode, if retriggerable setting is not configured (terminals B and B are left vacant) the full time delay will lapse and the safety output contacts will open before the relay can be reset (corresponds with MSR and MSRED delayed outputs). ON-DELAY (RANGE,, ): Time delay starts when the single-wire safety input changes from LOW to HIGH. Safety outputs are activated after time has lapsed and L is still HIGH. SINGLE-PULSE JOGGING: The safety outputs are activated when both, the single-wire safety input L and B are HIGH. It remains active until the set time has lapsed. When one of the inputs changes to LOW, the safety outputs are deactivated immediately. B acts as an automatic/manual start to trigger the Jog function while L monitors the safety device through a base unit. If there is any malfunction, the JOG switch should be replaced.

Press the Unlock request to start the timer. After the configured time delay expires, the lock command is powered to allow the safety gate to be opened. The GLP is designed for two types of applications: Category Stop: When the Unlock request is made, the Y output turns off to allow the stopping function to begin. When the GLP detects that the speed is below the stopped speed, the lock command changes state (depending on whether -To-Release or - To-Lock was configured). Safe Limited Speed: When the Unlock request is made, the Y output turns ON to allow slow speed operation. When the GLP detects that the speed is below the SL speed, the unlock command is turned ON. Setting the configuration:. Start configuration/overwrite: With power off, turn rotary switch LOGIC to position to configure X and X as saftey outputs, or position to configure X and X as pulse test outputs for safety inputs. unit up.

8 Bulletin R Proximity Sensor Configuration The GLP is designed to operate with two PNP sensors.. The proximity sensors can detect a geartooth arrangement where the ratio of the space to mark is :.. The space must be at least twice the diameter of the sensor. The mark must be at least twice the width of the space.. The proximity sensors must be set back from the mark no further than % of their rated sensing distance, Sn. Note: The distance of. Sn is required to achieve maximum speed.. The depth of the space must be at least times the rated sensing distance.. The distance between the sensors must ensure that both sensors are not off at the same time. d d Prox d Prox max.. x Sn min. x Sn mark space mark space mark d d Publication R-SGB-EN-P

9 Bulletin R Typical Wiring Diagram Light Curtain and Dual Channel E-stop, Manual Monitored Here the logic is set to, which will AND and IN. The single wire safety input is set to OR with the standard safety inputs so the relay ignores the fact that no input is coming to L. This logic can be applied to the DI and DIS.

10 Bulletin R E-stop, Safety Mat, Light Curtain and Interlock Switch, Monitored Manual Here the DI to the left will AND the and IN inputs. The single-wire safety input is ignored. The DI on the right will AND, IN and the single-wire safety input (L). For the safety mat input, S is wired to S and S is wired to S (opposite of N.C. safety switch wiring) so the relay recognizes that a mat is wired to the input rather than a N.C. safety switch with a cross fault. If the E-stop or the OSSD devices are tripped, all outputs on both relays will turn off. If the mat or interlock switch are tripped, only the outputs to K and K will turn off.

11 Bulletin R Proximity Sensors, Guardlocking Interlock, E-Stops, Monitored Manual Two PNP output proximity sensors are used to monitor the speed of the motor. The GLP LOGIC switch is set to, which configures the GLP for Safe Limited Speed and IN OFF. The single-wire safety input is ignored. The DIS LOGIC switch is set to, which requires and IN and L to turn its safety outptus ON. Press the Lock & button to activate the single wire safety output of the GLP. Press the button (for the DIS) to activate the safety outputs of the DIS and enable the motor to start. When the Unlock Request is pressed, the Y output of the GLP turns ON. This signal is intended to be used by the machine control system to run the motor at a safe limited speed of less than Hz (SL switch setting = ). When the motor speed reduces below Hz, the guardlocking switch is unlocked. If the motor exceeds the Safe Limited Speed, the single-wire safety output turns OFF, which turns off the DIS and therefore turns the motor OFF. The Single Wire Safety output of the GLP will also turn OFF, if the motor exceeds Hz (SL switch setting = ).

This changes the behavior of X and X to pulsed outputs, and the inputs S and S are expecting OSSD signals from the safeguarding device. Two PNP output proximity sensors are used to monitor the speed of the motor. The GLP LOGIC switch is set to, which configures the GLP to Category Stop with IN OFF. The single-wire safety input is ignored. Press the Lock & button to activate the X and X pulse outputs. The contactors pull in and enable the motor to start. When the Unlock Request is pressed, the Y output of the GLP turns OFF. This signal is intented to be used by the machine control system to initiate a Stop command. When the motor speed reduces below Hz (SL switch setting = ), the guardlocking switch is unlocked and the X and X safety outputs turn OFF. The motor now coasts to a stop. The safety outputs of the GLP will also turn OFF if the motor exceeds Hz (SL switch setting = ).
