    • minimum 6 or 12 pulses per minute* • maximum 2400 pulses per minute Shipping Weight • 2 kg (4.4 lbs.) Approvals • CSA • not CE compliant Selected via a common jumper. Refer to Operation. Page 2 Milltronics ZSS – INSTRUCTION MANUAL 7ML19985DF01...
  • Page 7: Installation

    Note: In climates where direct sunlight may cause the Milltronics ZSS temperature to rise above the specified limit, shade the unit by installing a sun shield.

    Voltages lower than specified will result in an inoperative condition. Vol higher than specified will severely damage unit. For 5 second time delay and minimum 12 ppm range, connect jumper across 1TB-7/8. Page 4 Milltronics ZSS – INSTRUCTION MANUAL 7ML19985DF01...
  • Page 9: Zss Typical Wiring

    ZSS contact to latch. In such a case, program a timer contact into circuit. CSA requires a 3 A or less fuse to protect contacts. For 240 V AC, protect contacts with a 1500 VA transformer as well. 7ML19985DF01 Milltronics ZSS – INSTRUCTION MANUAL Page 5...
