Glossary

Acceleration Delay: This function is used to set the time interval between acceleration relay (i.e. conduction-delayed time of acceleration relay) in two speed applications. In crane applications it prevents the crane to start motion with the highest speed (avoides motor damage).

Auto OFF (Rx): This function turns off receiver after a given idle time. Receiver MAIN relay will be turned off automatically. Normally this function is associated with "non-continuous transmitting" mode to prevent any unintentional radio signal reception.

Auto OFF (Tx): This function turns off the Transmitter after a given idle time while transmitting the signal to switch off receiver main relay. *Only available under "continuous transmitting" mode.

Channel Setting: Operating frequency of your remote control. There are CH:XX to CH:XX available, user is allowed to select any channel which is the smallest interference channel to operate.

Dual Motor Control: Through the software setting, F21-E2 remote controller allows to use A and B two single-speed buttons to proceed dual motor simulation control. In this way, the flexibility and cost savings can be substantially increased.

Group Toggle: Motion is the same as Toggle. The difference is when you press the same button; the relay still remains ON until another Group Toggle button is pressed. This Feature also can be programmed for different needs to setup a group of buttons to execute Toggle function. For example, control of multiple cranes. Remark: Can be setup as 4, and 6, up to 8 buttons group toggle.

Inching: The relative relay will be conducted within a certain time, in order to operate with short and precision movement. There are two kinds of inching modes: Normal Inching: Turn the rotary key switch (KEY) to "START" position and hold it, then press the relative motion pushbutton to perform inching motion. (When "Normal Inching" is chosen.) Toggle Inching: Turn the rotary key switch (KEY) to "START" position, then it can perform inching motion. To release this function, just turn to "START" pushbutton again. (When “Toggle Inching” is chosen.)

Inching Time: “Inching time” can be set from 0.01~2.0 seconds. This function is used to operate crane with short and precise movement (e.g. accurate position). “Inching Time” is the same as the working time for the relative relay that is controlled by executing “Inching” control function.

Interlock: Groups two pushbuttons in the following way. When the two pushbuttons are interlocked; it’s not possible to operate both functions at same time. In crane applications restricts both up and down motions in the same time.

Interlock Delay Time: Is the delay time which will be forced in activating the relays between 2 opposite pushbuttons when being pressed one after another. i.e.: while crane is moving in one direction (forward), moving opposite direction (backward) immediately would be dangerous especially when crane is hooked up to a heavy object.

LED OFF Time: This setting allows you to select the LED intermittent time to save transmitter power. i.e.: If 1 second is selected, the LED will be lit every 1 second.

Magnetic On/OFF: Both pushbuttons are used to operate the same relay. Press the "Magnetic ON" pushbutton to activate the relay. If the operator wants to de-activate the relay, he must keep pressing the "Magnetic ON" pushbutton and then press the "Magnetic OFF" pushbutton in the meantime. The purpose is to prevent the operator from accidentally pressing the "Magnetic OFF" pushbutton and dropping the load held by the magnetic disc.

Non-Interlock: Removes interlock. The two pushbuttons can be operated at the same time.

Normal: The relative relay is "ON" when the pushbutton is pressed and held; and relay is “off” when the pushbutton is released.

ON/OFF: Both pushbuttons are used to operate the same relay. Press the ON pushbutton to activate the relay and press the OFF pushbutton to de-activate the relay.

ON/OFF/ON: This function will set up pair of buttons to control two relay outputs: When one of the relays is turned on the second is always turned off. If one needs to turn on the second relay by pressing and releasing the corresponding pushbutton, this setting will first force to shut down the first relay, then the operator must press the same button again to turn on the second relay. This function can prevent an instant reverse motor operation, it is helpful to prevent accidental damage.

Passive Act: Refers to the operation of the receiver over a particular time (factory setting is 0.5 seconds) when receiver does not receive correct signal. There are two modes available. When you select “Relay-Off” (Stop motion), only the motion relays go to OFF status. The Main relay is still ON. In this mode if the correct signal is received again, then remote can be operated without rebooting. When you select "Power-Off" (Shutdown), it means that the Main relay will be turned OFF (non-conducting). You will need to reboot the remote system to continue operating. This function will be activated only if the range exceeds the maximum operational range or the transmitter signal has been disturbed for more than 0.5 seconds.

Passive EMS: This setting allows the user to select the duration of interference to be bypassed. If the duration of interference lies within Passive EMS setting, then the receiver is still in operational mode, and not affected. When the duration of interference is longer than the setting, then the receiver will stop working. Usually, this action is called "Passive EMS".

Save Power: This function is used to turn off the Transmitter after a given idle time. *Only available under “continuous transmitting” mode.

Toggle: Maintained function: the relay is operated by pressing and releasing. Press the pushbutton and release once for "on"; press and release again to turn off the relay. For example, control of lighting.

Transmit Mode: Non-continuous transmitting mode: After " Power-On", the transmitter will transmit the signal only when the pushbutton is pressed. This mode can save the power of transmitter. "Continuous transmitting mode": Transmitter will continuously transmit signal once transmitter is being Power-On.

Two Speed Control: Through the software setting, F21-E2 remote controller allows to use A and B two single-speed buttons to proceed two-speed simulation control. In this way, the flexibility and cost savings can be substantially increased.
