When the active window indicator is in

keys will increment 

and decrement the indicated digit. The 

◄►

 keys will move between digits. This indicates how long the 

shutter will be closed (when the shutter is not connected it indicates the “low” time of the TTL output 
trigger). 

 

NOTE

: If active window indicator is in the 

TIME CLOSED

 quadrant when the shutter is enabled, timing will begin 

with the programmed

INTERLOCK and ALARM

 

 

Using the Safety Interlock - Connections and Operation 

 

The SC10 is equipped with a Remote Interlock connector located on the rear panel (Refer to Figure 1).  In order 
to enable the controller, a short circuit must be applied across the terminals of the Remote Interlock connector.  In 
practice this connection is made available to allow the user to connect a remote actuated switch to the connector 
(i.e. an open door indicator). The switch (which must be normally open) has to be closed in order for the unit to be 
enabled. Once the switch is in an open state and an SH05 is connected, the shutter will automatically close. And 
the display will flash “

INTERLOCK OPEN

”. If the switch returns to a closed condition the shutter must be re-

enabled at the unit by pressing the 

ENABLE

 switch. 

 

All units shipped from Thorlabs are configured with a shorting device installed in the Interlock connector.  If you 
are not going to use this feature then you can leave the shorting device installed and the unit will operate normally 
as described in the procedures above. 

 

If you wish to make use of the Interlock feature you will need to acquire the appropriate connector mate and wire 
it your remote interlock switch.  Next, remove the shorting device by unscrewing it from the input and install the 
connector into the Interlock input. 

 

The Interlock input only accepts a 

2.5mm mono phono jack

.  This connector is readily available at most 

electronics stores (Radio Shack, Digikey, Mouser, Allied to name a few). 

 
 
 
The electrical specifications for the Interlock input are as follows: 
 
Type of Mating Connector: 2.5mm mono phono jack 
Open Circuit Voltage: +5VDC with respect to Chassis ground 
Short Circuit Current: 0.5mADC 
Connector Polarity: Tip is +5V, Barrel is ground 
Interlock Switch Requirements: Must be N.O. dry contacts (under no circumstances should any external 
voltages be applied to the Interlock input)

ALARM 

The SC10 has an Alarm feature when used in conjunction with an SH05 shutter. In the event that the shutter does 
not close within 30 ms of the deactivation voltage (Shutter Closed State) the display will indicate an “ALARM” 
condition. This feature is only active when the SH05 shutter is connected.
