OVER & UNDER VOLTAGE CONTROL RELAY GKM-01 & GKM-11
Voltage control relays are designed to protect devices with
sensitive operating voltage values from failures that may be
caused by mains voltage.
General
Device Usage and Working Principle
Make the connections of the device in accordance with
connection scheme. Set the required settings of the device
according to the operating voltage values of the load. When
the device is energized, if the voltage values are normal
according to the set values, the relay gets activated and the
relay LED ( ) is turned on. When the voltage values go out of
the set values, the related fault LED is on, it waits until the
delay time (DT), after the time has elapsed, the relay gets
de-activated and the relay LED goes out. When the voltages
return to their normal values, the device waits until the reset
time (RT), after the time has elapsed the relay gets activated
and the relay LED is turned on.
Required Settings and Error Notifications
HV Control Knob: High Voltage Set Value, when the voltage rises above
this value, HV LED is on.
LV Control Knob: Low Voltage Set Value, when the voltage drops below
this value, LV LED is on.
DT Control Knob: Delay Time, is the time to wait before entering the
failure.
RT Control Knob: Reset Time, is the time to wait for the relay to pull when
the voltages return to normal.
Switch off the device and release from connections. Clean the trunk of device
with a swab. Don’t use any conductor or chemical might damage the device.
Make sure device works after cleaning.
Maintenance
Warnings
-Please use the device according to the manual.
-Don’t use the device in wet.
-Include a switch and circuit breaker in the assembly.
-Put the switch and circuit breaker nearby the device, operator can reach
easily.
-Mark the switch and circuit breaker as releasing connection for device.

High Voltage Protection - To enter the error state: If the voltage, goes above the high voltage set
value, the HV LED is on, the device waits until the set delay time (DT), after the time has elapsed the
relay gets de-activated and the relay LED is off.
Low Voltage Protection - To enter the error state: If the voltage, goes below the low voltage set
value, the LV LED is on, the device waits until the set delay time (DT), after the time has
elapsed the relay gets de-activated and the relay LED is off.
High Voltage Protection - Exiting the error state: When voltage, lower than 5 volts of the set high
voltage set value, the device waits for the reset time (RT). After the time passes, the HV LED is off,
the relay gets activated and the relay LED is on.
Low Voltage Protection - Exiting the error state: When voltage is higher than 5 volts of the set high
voltage set value, the device waits for the reset time (RT). After the time passes, the LV LED is off,
the relay gets activated and the relay LED is on.
Protection Functions
Relay is Activated: 2 (COM) and 3 (NC) short circuit, 1 (NC) and 2 (COM)
open circuit.
Relay is De-activated: 2 (COM) and 1 (NC) short circuit, 3 (NC) and 2
(COM) open circuit.
Relay Activated/De-activated Status
The Low Voltage Protection function is deactivated when the
LV control knob is set to Off. (It's only on GKM-11.)
The Off stage is limited to 140V. If the voltage falls below
140V while in this stage, the relay is deactivated and the LV
Led is flashes.
The High Voltage Protection function is deactivated when the
HV control knob is set to Off. (It's only on GKM-11.)
