Rev 9 02/14
Tymetal’s Model MGT Gate Reversing Edge Transmitter is
compatible with the APeX Controller used in Tymetal’s swing
and slide gate operators. The MGT transmitter is designed
to connect to normally open gate edge contacts and is fully
supervised.
During normal operation, when the edge contact detects an
obstruction while the gate is moving, the MGT transmitter
will send an obstacle signal to the APeX Controller and stop
or reverse the gate.
Being supervised, the MGT transmitter sends
hourly
status
reports. It also sends trouble signals to the APeX Controller
when the transmitter detects a trouble condition. When a
trouble signal is sent to the APeX Controller, the run alarm
sounder will beep fast and continue beeping for five minutes,
then the sounder will chirp every five seconds while the gate
is idle.
To clear the trouble annunciation at the gate, the
transmitter’s trouble condition must be corrected first,
then the Controller’s power must be cycled off and on.
Four conditions regarding the MGT transmitter can cause
the APeX Controller to sound the audible trouble warning:
• MGT transmitter case has been opened.
• Disconnected or shortened reversing edge when MGT
transmitter edge supervision is enabled.
• Low batteries in the MGT transmitter.
• Hourly supervision signals from the MGT transmitter
have not been received by the controller.
MGT Transmitter Troubleshooting
When troubleshooting an MGT transmitter, first open the
MGT and check the unit’s internal indicators. The POWER
indicator should light when the reversing edge is pressed or
the TEST button is pressed.
If it flashes, the batteries are
low.
The LOOP TROUBLE indicator will light when the TEST
button is pressed
if
the SENSOR TEST jumper is enabled
and
the reversing edge wiring is open or shorted.
Tamper Supervision
The MGT transmitter contains a spring loaded tamper switch
that detects if the case is open. When the case is opened,
the transmitter will
immediately
send a trouble transmission.
Anytime the transmitter is serviced, you will need to open the
case.
After closing the MGT case, cycle the Controller’s
power to clear the trouble annunciation.
Edge Supervision
MGT transmitters can monitor the connection to the gate
edge if the gate edge is equipped with an internal 100µf
capacitor. There is a jumper in the MGT that enables or
disables the gate edge connection monitoring. If edge
monitoring is enabled, and the connection to the gate edge
is open or shorted, the MGT will send a trouble transmission
with the next hourly status report
to the controller .
Use
the transmitter’s jumper to disable edge supervision
if the reversing edge does not contain a capacitor (the
trouble loop indicator stays lit in the MGT transmitter).
The jumper does not affect the transmitter’s hourly status
reports.
Low Battery Supervision
MGT transmitters monitor their battery condition and will
send a trouble transmission
with the next hourly status
report
to the Controller when the battery tests low. Replace
the batteries, close the MGT case, and power cycle the
controller .
Status Supervision
MGT transmitters send
hourly
status reports to the
Controller. The Controller expects those hourly status reports
(this cannot be disabled in the APeX Controller). When the
controller counts four missing transmitter status reports,
the trouble annunciation will occur. This could occur from
transmitter trouble or poor radio reception by the controller.
Open the MGT and test the transmitter by viewing it’s
indicators and pressing on the reversing edge. If the
transmitter tests OK, check the radio range of the Controller
using a handheld transmitter. If a handheld transmitter
cannot reliable activate the operator at the distance the MGT
is from the controller, remotely mount the local antenna or
use an external receiver antenna (Model EXA-1000 or EXA-
2000). Also, Tymetal’s Model FT-1 Radio Interference Field
Tester can be used to test the installation for abnormal radio
interference conditions.
