Assemble the FlexMod Dual Output Voltage Sensing Relay
& Timer in the following sequence (using the 12805 Mating
Connector Kit):
Warning: Disconnect the vehicle's battery before installation.
Required Connections:
1. Connect pin 1 (OUTPUT1 Trigger) to a circuit that is
energized whenever the ignition switch is in the run
position or to a SPST Mom-On switch.
2. Connect pin 2 (BATT -) to ground.
3. Connect pin 3 (OUTPUT1) wire to the positive side of the
load (10 amp max). Connect the negative side of the load
to a local ground.
4. Connect pin 4 (BATT+) to an appropriately sized fuse.
Connect the fuse to the positive terminal of the main
battery.
5. Connect Pin 5 (OUTPUT2 Trigger) to a circuit that is
energized whenever the ignition switch is in the run
position or to a SPST Mom-On switch.
6. Connect Pin 6 (OUTPUT2) wire to the positive side of
the load (0.2 amp max). Connect the negative side of the
load to a local ground.
7 . To ensure proper environmental sealing, all unused
connector pins must be sealed with blanking pins.
(See specifications section).
Normal Operation Summary
This summary describes the factory default settings.
Programmable units may have different voltage and or time
delays.
Note: 12V system limits not in parentheses (24V system limits
in parentheses)
Required Connections:
1. When the trigger input is energized, the Voltage Sensing
Relay Timer will energize the load, solenoid, or relay.
2. When the trigger input is switched off, the Voltage
Sensing Relay Timer delays for the delay period and then
de-energizes the load, solenoid, or relay. If during the
delay, the battery voltage drops below the factory set
disconnect voltage for one minute, the load, solenoid, or
relay will be de-energized.

Additional Operating Details
Overcurrent Protection
Only pin 3 is overcurrent protected, pin 6 is not overcurrent
protected. Exceeding 0.2 amps on pin 6 will render the entire
module permanently inoperable.
• If the PIN 3 current exceeds 15 amps for one second,
Pin 3 will be turned off. To reset from this fault, the Timer
must be powered down.
Abnormal Voltage
• If the BATT+ voltage is less than 8.5V (16V) or greater
than 17V (34V), PIN 3 (OUTPUT1) and PIN 6 (OUTPUT2)
will be turned off. The Timer will auto-recover when
BATT+ returns to normal.
