remote indication
gHCK-drI
A simple remote indicator is available as an option, which provides indication of the status of the GCHK-100.
The GCHK-DRI has all three status lights that are normally visible on the GCHK-100 as well as a reset button.
This allows the relay to be monitored conveniently and RESET if necessary. The relay may also be tested by
pressing the RESET/TEST button twice quickly.
The GCHK-DRI is flush-mounted in a panel with four ½ in x 6-32 screws with nuts. A rectangular opening of 82 x
51 mm (3 1/4 x 2 in) is required for mounting as shown in Figure 11.3.
A 5-conductor cable with 22 gauge or larger conductors may be used to connect the GCHK-DRI to the
GCHK-100 relay. No shielding is required. No additional power supply is required to power the indicator.
Figure 5.1 shows the faceplate of the GCHK-DRI. This simple indicator extends the 3 red LED’s and yellow push
button on the GCHK-100 to a panel or remote location. Press the yellow button once to reset the relay or twice
quickly to test (Warning: a test will cause the GCHK-100 to trip).

mgard-SYM
The mGARD-SYM is a remote display indicator that is used in conjunction with I-Gard Corp. relays. The
indicator has the capability to interconnect with up to 50 GCHK-100 relays in a bus network topology and
provides detailed device status information.
The display has a 4-line screen that shows a list of connected devices. A device can be selected and viewed in
detail. The relay mode, delay and trip level settings can be viewed (but not altered). The reset and test functions
can be performed directly from the display.
Fault levels are displayed as a percentage of the selected trip level. If the trip level is 1 Amp and there is a
500 mA fault current, the reading on the display will appear as 50%. Ground check resistance and frame voltage
are also displayed as a percentage of the trip setting. Screen navigation is done using a 4-button interface.
The menus are displayed on the right side of the LCD, the left side is reserved for viewing relay information.
