LynTec PDS-10 series Power Delay Sequencer

❏

❏

❏

Relay based power sequencer for sound systems — Turns on front-end gear fi rst, power amplifi ers last

Protects expensive loudspeaker systems from damaging power-on or power-off click & pop transients

❏ Tested, complete package — low labor — mount next to any

circuit breaker panel to sequence AC power "hot" lines

❏ Time proven, reliable, G-E RR7P3 latching relays snap in and

have low voltage plug-in connectors

❏ Low power consumption — no continuous relay coil current

— runs cool for long life

❏ Diagnostic LEDs and internal ON - OFF test switches speed

installation for testing and troubleshooting

❏ Cabinet and all components connected to high voltage are UL

listed — low voltage electronics are isolated.

❏ 4, 8 or 10 20/30 A circuits — 120 or 240 volt models available

❏ Up to 6 One Touch remote control

locations possible

❏ Kill function uses external contact
for instantaneous shutdown.

❏ HurryOff function shuts down
immediately if you hold down
any OFF button for 2 seconds.

Great for Ohh.... no........ situations.

❏ Daisy-chains for unlimited circuit
count. Interfaces with LynTec
MSLC, MSP, SLC, SP or multiple
PDS sequencing systems.

New Features

❏ Multiple delay options.

❏ Variable step rate

❏ Completion contact option on last step

can be used for additional indicators
or to trigger more equipment.

How they work
Applies AC to low level, front-

end electronics... waits for them
to stabilize... (clicks and pops are
ignored by un-powered power
amplifi ers)...

AC is then sequenced to power
amplifi ers spreading high inrush
currents over time.

SS-2 Sequencer Switch Set

One SS-2 switch set is supplied with each panel.

139-0512-00.1 Pa g e 1 of 4

Protects valuable loudspeaker
systems by delaying turn-on until all
low level equipment has stabilized.

How it works

When an ON button is activated, the on LED starts
flashing. Steps 1 to 10 are activated with delays as
determined by selected jumpers. The process is reversed
when the OFF button is pressed.

ZipOff

2 seconds after power fails, all relays will zip-off, shedding
the load. System will automatically re-sequence when
power resumes.

KILL

Connecting the KILL terminal to common will light the
KILL LED and trigger ZipOff, turning off all relays. When
the KILL contact is opened the KILL LED will extinguish
and the on sequence will resume.

HurryOff

Holding down the OFF button for 2 seconds will invoke
ZipOff without an automatic restart. Press ON to restart.

Relay drive capacity: One RR7 coil (530 mA. max.) NEVER parallel relay coils!

Relay ON/OFF pulse width and spacing: Variable

RELAY SOURCE — ZIP-OFF LOAD SHEDDING

The +35 volt internal dc relay supply has a PULSE CURRENT indicator for visual as well
as aural troubleshooting. Each time the LED fl ashes a relay should click.

All latched-on relays are zipped-off 2 seconds after power fails, shedding the load.
ZIP-OFF minimizes the surge load when power resumes.

The sequencer remembers if the system was ON and automatically re-sequences
when power resumes. No manual reset is required.
Short protection: A 0.75A Fuse protects in the event of a short.

REMOTE CONTROL CHARACTERISTICS

A momentary contact from ON or OFF to COMmon is required to activate the ON or
OFF function in the sequencer

The SS-2 Sequencer Switch Set (one set supplied, up to 6 supported) provides
easy-to-mount switches, with built-in fi lm legends, to remote control the AC power.
Switches are IDEC AL6 series.
