Status and Error LEDs
The SyRen 50 has two indicator LEDs. The green LED
marked status is used to communicate various information
about the current state. Its operation depends on the
operating mode. For example, if a lithium battery pack is
selected, the status LED blinks the number of cells detected. Unless you are in lithium mode, the
status LED will usually remain on.
The Error LED illuminates if the SyRen has detected a problem. It will light if the driver has shut
down due to a depleted battery or due to overheating. If you are using a NiCd or NiMH battery,
and commanding an acceleration causes the motor to jerk and the Error LED to flash on and off,
the battery is depleted.
Mounting your SyRen
The SyRen is supplied with four mounting holes. These can
be used to attach it to your robot. The centers of the
mounting holes form a X” x X” rectangle. The holes are
.125 inches in diameter. The proper size screw is a 4-40
round head machine or wood screw. Four 1” long machine
screws and nuts are included.
