2.6.3 Connecting the Recorder Outputs
IMPORTANT: Ensure that the power is off before proceeding.
Connect your recorder to the lower terminal block on the back of the MTS6
(pins 14 and 15), as shown in Figure 25 and Figure 26 on page 19.
IMPORTANT: To maintain good contact at each terminal block and to avoid
damaging the pins on the connector, pull the connector
straight off (not at an angle), make cable connections while the
connector is away from the unit, and push the connector
straight on (not at an angle) when the wiring is complete.
2.6.4 Connecting the Relays
Note: The customer will provide their own cable for connecting the alarm
relays. Acceptable cables range from 16 to 26AWG.
The MTS6 has one fault alarm relay and two high/low alarm relays. Each
alarm relay is a single-pole, double-throw contact set that contains the
following contacts:
• Normally Open (NO)
• Common (C)
• Normally Closed (NC)
